Physically, he is the strongest of the Norse Gods, but his rage can produce lightning > https://norse-mythology.net/thor-the-god-of-thunder-in-norse-mythology/

Anyway, i agree. Barbarians for eg, coud get an power of not only enter on range, but when reach high level, enter in a "berserk" state, gaining +8 STR, +6 DEx, +4 CON, DR 20/fire/cold/electricity, increased speed and regen. For social interations, an huge bonus to intimidate after lv 10 sounds interesting too. About Japanese things, i usually don't like much Japanese games. Dark Souls and Dragon's Dogma are the exception.

About monks,i read the 5e rules and yes. Monks got unnecessarily nerfed. Furry of blows, movement speeds, bare hands damage, everything got nerfed. Sadly, because monks was never OP.(unless multi classed on 3.5e, but an better solution was just to make monk feats unavailable for non humanoid creatures)
