didn't really expect talents to be changed or added at this point, but i still find it interesting to think about stuff that COULD have been fun^^

regarding your Leech suggestion, sounds interesting, but it would also require some way of visually differentiating a character's own blood from the blood of others. like giving other's blood a glowy or animated texture or something like that.

and regarding Glass Cannon, 4 ap for -33% hp would probably be too strong, but i would like to see it being 33% for 3ap or even 25% for 2ap. less hp for more ap sounds great for many builds, but cutting hp in half means the character might well go from full health to dead in one or two enemy 'turns', without you having any way of stopping that from happening. that doesn't really sound like it's worth taking, nor like it would be fun to play.
