PoE Independent-Lab7944 builds

Hi - I'm quite casual. This is the first league I've sunk a lot of time into the game in a while. I suck at dodging mechanics and need to be decently tanky to enjoy the game. Is there anything I can do to improve my damage on my build that doesn't break the bank? Should I realocate some points in my tree? I run despair on hit because I map and it's more a quality thing. I self cast despair/temp chains on bosses which I think overrides cast on hit (unless I misunderstand the mechanic) I have about 5 div but would be willing to farm more. [
