For now, I suggest these criterias :
Good idea, i will edit my post arcordingly !
I edited the OP, and took suggestions from @Erokhi.
I decided against adding a short note to builds, as it would make the post very long in the end. Please choose a suitable title to give the basic idea to your builds instead 
Also separating my build from the OP!
Reasoning behind my class choices:
Oh, one more thing.
It shouldn’t be build of the day because people won’t change their playstyle in just 1 day. It’ll be tiring for you as well because you have to check up the new builds every day. I personally prefer Build of the Week/Month.
@Erokhi It will be changed to build of the week/month as time progresses Currently I want everyone to participate and theorycraft away builds to their hearts content, and I’ll add a spotlight to one everyday, but it will be changed to weekly around beta/release.
Reads the topic’s first post
Now we’re talking.
Here’s my Wizard/Chronomancer Build
I am not sure the usefulness of “Quick Cast” yet, if it’s redundant, I will go Wiz > Wiz > Psy > Psy > Chrono > Chrono.
My picked skills:
Energy Bolt (10/15)
As this skill can be charged on top of a small splash, this will IMO makes a spam-able main DPS skill.
Lethargy (5/15)
If I had a choice, I wouldn’t take this skill. This skill, I will only be using it on bosses mostly.
Reflect Shield (15/15)
As the name of the skill implies. Mages by nature is squishier than their counterparts, thus I think this skill will be useful for heated situations.
Sure Spell (10/10) This skill level is still unconfirmed, but if duration is at least 15 seconds anywhere in between, I will use the rest of the points on Energy Bolt.
Your next skill after activating this buff cannot be cancelled by being hit. The reason why I feel 15 seconds is reasonable is because I love “contingencies” 
Quick Cast (5/5)
So far all mage skills doesn’t seem to take a long time to cast. This skill usefulness will be the deciding factor if I’m going to take this class path. If proven useless, I will take the path of being a Psy.
Electrocute (5/5) -Filler Skill-
No description as to why I take this skill.
Stone Curse (5/5) -Filler Skill-
No description too.
Prominence (5/5) -Filler Skill-
I did not take Hail because mobs will not stay there for you to hit them. However, hail will be a good skill if you’re in a party that mobs and kills. You can cast hail at a pre-determined spot, towards the direction of the lurer.
Quicken (10/10)
You became a chronomancer because of this skill. No explanations needed, right?!
Samsara (1/10)
I have no idea the usefulness of this skill, so I kept it at level 1.
Stop (9/10)
The only sad thing about this skill is that, stopped monsters cannot be damaged. Good team-saving/self-saving skill.
Slow (4/10)
I do not know what possessed me to take this skill to level 4, but I intended to keep it at level 1 or not get it at all. Maybe I got this because Back Masking & Samsara CD is incredibly long. Hahaha!
Haste (5/5)
Likewise, you became a Chronomancer for this skill too, didn’t you?! No explanations needed then? 
Back Masking (1/5)
Long CD. But if this skill can be used to save the party from being wiped or a class with major role from death within that split second, I will get this at 5 and unlearn Slow.
Please advise on my chosen skills above! I’m very new at this and I am definitely very open to opinions.
Edit:
I forgot I had to explain why I think it’s a good(not so good ughhh) build, what I can do with it and etc.
I think this build is very well-balanced between offensive, defensive and support.
In times of boss slaying, your quicken on a major DPS class (such as Ranger) and lethargy skill on boss becomes essential.
For normal grinding, (especially in a small enclosed area), Prominence is so sexy! Just think about it, jumping flames for 15 seconds!!! XD Mostly you’ll be kiting with charged energy bolt. If things turn nasty, you can drop a reflect shield or use the famous combo: stop, haste and fleeeeeeee!
That’s all I can think of for now, I hope you guys liked this build. But yeah, do share what you think/areas of improvements!
awesome to see another chronomancer build, but you choose elementalist and not psycokino, because they dont have stone curse. 
I thought stone curse is an elementalist skill? or am I reading it wrongly? 
I am confused 
I thought telling because you wrote Wiz > Psy > Psy
Sorry if I confused you, in the guide above I wrote the following: I am not sure the usefulness of “Quick Cast” yet, if it’s redundant, I will go Wiz > Wiz > Psy > Psy > Chrono > Chrono.
The build I made for myself is Wiz > Wiz > Wiz > Ele > Chrono > Chrono
In the 3rd Wiz, there is a skill called “Quick Cast” If that skill is useless, I will go Wiz > Wiz > Psy > Psy > Chr > Chr instead.
Hope that clarifies! 
yep it does 
Chronomancer - Linker/Thaumafurge build: Battle Chronomancer
wizard - wizard - linker - thaumafurge - chronomancer - chronomancer
Build link: http://www.tosbase.com/tools/skill-simulator/build/vf045j9cl5/
Explanation:
This build should represent some battle wizard action, as it should be some kind of tribute to the berserk wizard in ro. Instead of using magic, you are using different skills to improve your situation and use some sick thaumafurge skills to increase your atk and others, sadly the best thaumafurge skills are on tier 2 but then you cant get to chronomancer anymore, so I decided to let it on tier one, linker is also important for being able to attack mobs and inside of a party, chronomancer to higher your atk speed and others, also beeing able to have a better control over the situation.
in the early game as wizard, you are already skilling smiliar atk to int, as you are rather using your melee attacks than energybolt to damage your opponent, the different skills should help you and the party to make the opponents easier, as linker you should be able to help the party much and also level faster through mob killing, later on with thaumafurge you are beginning to get a beast through the buffs and debuffs of the enemies, with the chronomancer you are able to make your stronger atks faster also beeing faster to move is quite convient
in the end its questionable, if you rather want 2 tier linker + 2 tier thaumafurge instead of 2 tier chronomancer, but i really love high atk speed, specially as wizard.
no thats another one 
the first one is more like control pressure, you can stop the monster and keep the damage flowing, while the other build is a battle chronomancer, where you fight with your fists instead of magic.
should I have edit my previous post to add the build there? 
ups sorry -.-, fixed it 
@Tsugumi no problem, I love seeing what the community can come up with (and what I can use 
)
Looking forward to seeing what else everyone can come up with
Have you any idea how many characters can one account hold? I plan to make an alchemist too.
