Interesting, I tried Tigerheart on Karlach during Act 2, and I was very disappointed. The aoe damage is meagre and has only a very small area. Maybe I did something wrong. On many NPCs you cannot apply poison or let them bleed, so it's quite situational. If you can do it, I find the effects of the aspect of the last animal on the list (don't know the English name), maiming, much more interesting than the relatively small damage increase of the Tiger aspect.
In the end, I changed her back to Berserker (Barbarian 9/Rogue 3) with emphasis on throwing, it's a lazy approach, I know, but so nice and easy.
No, no. I think it used to be higher (normal damage applied to up to three enemies) but got nerfed alongside the cleave (AoE) option on axes (half damage applied to up to three enemies). It's essentially just what an axe can do, but as a class feature (?). Innate problem is that you need at least 3 enemies to do more damage than a normal attack.
Wildheart subclass suffers from false advertising (wolfheart) and being nerfed into oblivion (tigerheart). Bearheart + stallion aspect is the only really "decent" option in that it offers defense otherwise difficult to obtain. I'm not sure why they balanced it that badly, Berserker is really the normal way to go. There's just no comparison. You can go wildheart for fun and tankiness, but it's largely a trash subclass.
