So I'm not an expert, but I'll try. TLDR: I'd look up a wyvern or wolf guide and adjust your build.
Attack build with only one source of added flat damage on rings. Both %increased cold damage and %increased lightning damage on your rings. Your build's already confused on what it's scaling.
The first rend is building combo and living lightning, which get you power charges with pounce, but I'm not sure what the living lightning is for. PoB says they're doing 168.8dps and since you dont have chaos inoculation they can't be used for minion pact cause they only have 1hp and need 150% of you're hp.
Second rend looks like your highest dps for single target, but it's linked to Ancestral Call, Ambush, and increased aoe so it's only good once every three seconds and against groups of enemies with full hp?
You're stacking cooldown recovery but not using Lunar blessing like wolf builds. What are you using all this increased cooldown for? Just pounce?
Flame breath converts %100 of your weapon physical damage to fire and only does 116% of weapon damage as base, compared to rends 343%. Right now the ignite portion of flame breath is doing 9dps without any added from bhatirs. Oil barrage might be a better finisher at %250 weapon damage. You've only got 23.55% crit chance, so each time it re-rolls you're losing critical damage. It looks like you're trying to stack % added damage from bhatirs vengeance and blazing critical. You're adding all these more damage sources to relatively small hit and your bhatirs+blazing might be falling off before getting to the boss. If the boss has any elemental resistance they'll reduce your damage even more.
