I'm sure you can kill everything in the game by using Quen, dodging & spamming the appropriate bombs. Samum for crowd control, and then a dragon dream or grapeshot. Or just put Conflagration traps in plain sight and let the retarded enemies walk over them.
Since there's so much crap scattered about everywhere, crafting is not exactly a problem either.
Basically a "Green Goblin" Geralt, which would make a rather hilarious playthrough. Maybe I'll try it on a second playthrough. I'm focusing on swordsmanship, but the combat is pretty terrible.
