Talents, schmalents. Useless, every single one of them.
(Except Lone Wolf).
Just pop green tea + apotheosis, adrenaline rush and spam all your tier 3 source spells at the cost of 1AP and 0SP per, and have a nice day & watch as your foes disintegrate before your eyes without even having your 2nd-up character take their turn. Fight goes into round 2 and everything is on cooldown? No problem - just Skin Graft, adrenaline rush and repeat the process. Everything should be dead 3 times over at this point. Even Tactician bosses.
Seriously though, I was going to address your post but Stabbey pretty much mentioned all the same things I was going to say. But also seriously, the above strategy works and will usually yield a 1-round fight in almost any scenario once the tea is available and you're level 5 Poly.

Nice forum avatar BTW
