Some disclaimers to start. #1- Its potentially rambly, esoteric, unnecessary, and largely a matter of preference. #2- I have no expectations and was going to let it lie, but I've spent a long while thinking about it and decide to try to put it to words. #3- I'm bit of a modding addict and the time I spend looking threw and thinking about existing or potential modifications is excessive.

Wolfgang:
An S tiered character who by an metric is over powered. Role is designated ass kicker and his downsides are food when doing said ass kicking (easy to come by) and sanity which isn't actually a huge detriment and can actually be a boon.
My revisions are about balance, convenience, and experience in theory.

Sanity drain for night 1x, 1.5x for insanity aura. Reduce sanity gained from positve aura and dapperness by 25-50% - Having a greater passive drain means more passive nightmare fuel, a greater sanity loss around monsters means more potential nightmare interference in fights, lower passive sanity regen means active upkeep if you want to be left alone.

Wimpy: 0.9 scale, 0.5 dmg, 200hp, 1x hunger drain - In wimpy state your slower and non combative (if you're lucky) but the default as low as 100 hp is actually a boon for over coming attrition since you health percentage stay the same it'd be effectively 3x more healing once gone might. Its a sub optimal state for conserving food. - Triggers at 100 and below, Ends at 125+.

Normal - 1.0 sacle, 1.25x dmg, 200 hp, 1.5x hunger drain - Is actually a buff to dmg done though the the hunger being capped at 1.5x is a minor nerf since drain scales as you go up not give you the option of teetering just over wimpy to conserve. Reason being I'd like him to feel like a combat character even when not in complete woop ass mode. - Triggers at 125+, ends at 100 and below.

Mighty- 1.1 scale, 2x dmg, 300 hp, 3x hunger drain, 25% faster - Complete woop ass mode. Less model scale because it always seemed excessive to me but thats just aesthetics, Pros and cons always at max. - Triggers at 299+, ends at 125 and below.

Transformations aren't cancelable. - Its not the hardest thing to keep track of especially with static nature and broad range of each form in this iteration and he needs some liability for carelessness.

More below provided I'm not explicitly told not to, as the motive strikes to put it down and format it so its not complete cancer to read.
