Tired of Unity's cloth system....

I've cloth for flags and stuff like that works perfectly. But whenever i try to set it up with a characters clothes (i'm using weights on the mesh for the character's rig), Unity bugs out and i'm getting really tired of it. Am i doing something wrong or this engine is having more problems each update?

(Quick constraints for testing)


(When i press play, strangely the mesh seems all squashed up)
I kept the cloth part of the mesh with/without weighting and the results are always the same.
Anyone has a solution?
