I have a character in my party who has maxed out his strengh and is using the reckless strike action in his combat rotation.
Buy just schiving three hammers and one eagle he is doing around 20 damage (6 for strengh, 5 for weapon, 3 for extra damage and 6 again for the extra strengh bonus and one for thug bonus I think). I combination with pretty low colddown (2), he can pump it out very often. I don't think its balanced with the penalty that you must put 2 recharge tokens on a active defence to use this ability, becuse its not that much and you can always put it at at the same one, or one recharging... But what do you think? I just reflected about this, as the insanly good Double Strike got nerfed too.
