Some Wolfgang Observations/Suggestions

[Raven Idol]

I've been warming up to Wolfgang lately, after his skill tree, but there's a couple things I'm not the greatest fan of.

Mightiness: I kinda feel like Mightiness is a little too easy to maintain. Mining, combat (I think), dumbbells, and the Gym all refill your meter, but it also drains very slowly. I feel like being Mighty should be a more periodic thing, rather than so easy to maintain that it might as well be his default state. 

Dumbbells as weapons: I like that they can be utilized as weapons, but there's something that bugs me, which is losing durability just by throwing it. Could it maybe only lose durability on hit? I don't see why missing should eat a not-insignificant amount of durability.

I think those were my only problems, at least that I can think of currently.
