Leech: If you get hit, then you heal like 15-30 hp. Later in the game that is less than 5% of your HP pool... The talent is certainly helpful at the beginning of the game, but is far from being overpowered, it is actually a completely useless skill later in the game.
Congratulations, your post has made me make an account for these forums. Leech heals you 5% of your maximum hp, so it is never useless, and, given enough hp, can make you just as invincible to attacks that make you spill blood as any other skill. Got 3,000 hp? Enemy hits you with a slashing weapon for 150? Enemy just wasted the AP from that attack.
Not to mention of course the Bleeding status as mentioned everywhere else.
