PoE Exsanguinate, Trap builds with custom stat filters

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. [

Hit me with some knowledge! I have the +5% crit chance in the config for Brittle Boots. Is that right? Thanks guys! :\]

Here is my POB for my league trapper i have a little more room to squeeze but not much more in the direction ive gone with seismic trap. Its insanely tanky, easily one of the tankiest characters ive played in the past 9yrs . Has plenty of damage and has beaten all rolled invites, simu upto wave 30 but sometimes its iffy. Its fun to play imo, very strong and reliable damage. Would appreciate any commentary, you can drop determination for pride and get around 2 mil dps. Its in the setups to fiddle around with, you can also do some jiggling with precision and purit
