This is the build, I came up with.
I’m trying to make a Support build, i wanna keep Oracle (Rank 2) for Death Sentence. I just need help with stats for most part and maybe re-do the build. 
Death sentence isn’t a good skill with the current implementation. But if you are sure you want to take it, then here are some other inputs:
I would tell you to get only one point in Change and place the remaining points into either counter spell or prophecy. Both counter spell and prophecy are (in my opinion) the best Oracle skills. You might want to re-consider not maxing them? Counter Spell can be left lvl 4 for PvP, but for PvM I would max it (or get at least lvl 7~8). Prophecy should be as high as you can get seeing skill levels increase efficiency of the skill by a lot (duration and number of debuff blocks).
For PvM you don’t need aspersion level 15, it won’t lower monster’s damage by a lot. You could use those points into revive or mass heal, but that’s up to you.
Stone skin is mostly worth it only if you’re a very SPR focused build. If you don’t intend to get very high SPR, don’t bother much with stone skin either.
Oracle C2 is currently not a very good class for a rank 7. Hopefully it will get buffs in the future and maybe a cool C3 circle. But as for now, it’s not very good, so be prepared.
You will struggle a lot to level with a build like that. You have almost nothing to deal damage in solo play. You’ll have to beat monsters with blessing and cafrisun set till the end of the game. Be prepared to struggle a lot doing quests unless you have friends to play with you all the time.
For stats:
STR will only increase the damage of your first basic attack hit. You have no physical damage skills.
INT will only increase damage of your lvl 8 Cure and lvl 10 Heal. You only have 2 magic damage skills.
SPR will only increase effectiveness of your Stone Skin, if it’s really high (at least 2/3 of the points on all level ups spent on SPR), you can get something around 80% block rate just with stone skin alone in PvM.
CON will only benefit you with more HP, which is nice for a (conservative) support.
DEX gives you evasion, which enables you to make a more selfish support that survives better by yourself but not help others surviving so much.
In the end, I believe the best stats (for your build) would be 2:1 SPR/CON or full CON.
STR won’t benefit much. INT will only increase damage of two skills (which your Cure isn’t even level 10). and DEX is maybe only worth it if you want to PvP hard (but I’d be divided between it and going for SPR instead for stone skin).
Should I re-think the whole build, I could go for something less support.
Well that’s up to you.
If you want to be a full PvP build, it’s okay to make a build like this with full CON. In PvP more HP is never enough.
But if you want to PvM, well, think of it this way: 70% of your gameplay time will be spent solo doing quests or killing mobs. That means 70% of PvM consists of solo play. Therefore, I think it’s very important for a PvM build to be able to solo properly.
That being said, my cleric builds are usually oriented towards damage dealing. Supportiveness comes by default from the cleric classes. Stuff like revive, ressurect, counter spell, prophecy, will be good regardless of your build stats.
I have a chaplain oracle that I love to play with. He’s very good to solo (compared to other cleric classes) but his damage obviously doesnt match that of an archer or a wizard (which most, if not all, cleric classes can’t compete with). I consider myself a support because I took the SPR:CON path with a build very similar to yours, except I switched one rank of Oracle for chaplain.
I was considering getting Cleric 2 (or PD) at rank 7 for more heals too, but now with rank 8 classes almost being released, I might wait a bit more to see if Oracle C3 is actually worth it before changing into rank 7 as Cleric C2 or PD.
If you intend to take chaplain, which in my opinion would make your solo leveling life far easier than Oracle C2, I would recommend you to take chaplain asap though (meaning to leave Cleric C2 for R6 or R7), in order to have the most dps you can as soon as you can to facilitate leveling.
If you think like solo leveling is just “a small part of the game” and don’t want to focus on being good at it, or you always play with a friend who mains a DPS, then you can consider the build you first suggested but again, might want to think twice before taking Oracle C2.
I’m mostly PvM, i saw this build well looking for one to use. I’m not crazy for Plague Doctor. tbh
Well if you don’t like plague doctors then don’t make a build around them. 
Better make a class you think you’ll at least enjoy.
I kinda wanna play a melee dps build, i’m just clueless how to make one.
