instead of having someone feed you a line of builds the fun of Tos is making your own. I can give you tips of making a build I find to be useful.
Since you can make MULTIPLE character on your account, focus on 1-2 themes that really sync with each other. you do not have to stuff everything into one character. I feel like the wizard tree has the most unique utilities. the key is to sync them well together.
the next point is skills. it is better to look at skills rather than classes. one way to analyze skills is to count how many skills are actually useful
there are people who put down class paths but thats because they know the skills well and already know which skills are good.
for someone starting out, i suggest you analyze an entire main class (wiz, cleric, archer, sword) by looking at each class the main class has to offer. count how many skills are complete trash (because i assure u there are a few) and just delete them from the skill list. you would then choose a class path, and count how many skills remain in total. keep in mind their cooldowns as well.
the next important thing is to remember is that the game is designed for you to get rid of old skills and replace them with stronger, new skills as you go up. the scaling of a skill’s dmg is horrible. it usually doesnt go by % but by addition. keep in mind that entire classes might go useless because they simply dont scale. go for good utility and % buffs
the final point is to prepare for the future. this means that you should not plan your build to go until rank 7 but until rank 11. if you look at the costumes and names of the later ranks on wizards, you will find more utility based themes. this is my opinion but the niche of true dmg based ranks will be less than half, maybe 1:3. if you look at the color of the class symbols right now the ratio of dmg:utilities is 7:7 and MOST of the dmg based classes arent optimal (featherfoot, pyro falls off on dmg, wizardc3 which only relies on the 50% magic buff after 2 ranks, psycho falls off on dmg and is an unreliable source of dmg, rune caster has 2/5 dmg skills that have 8sec cast)
imo the future of wizards will lean towards a support utility role as a min part of their class pool rather than aoe dmg. with 1:3 or so viable dmg based ranks available this limits the dmg based class path to 1-2 with variations considering swordies and archers make no sense having much utility they will most likely end up being the dps dealers in the future.
so keep that in mind when making a build.
