Dude I
ing HATE master mode. I can waffle stomp pretty much every boss in the game and kill them within 10 seconds but enemies can sneeze on me and I die even with 80 defence. The snazzy pets and trophies aren't worth it.
If there were a difficulty between master and expert mode where enemies don't get insane damage and health buffs, I'd jump at it, but for now I'm just sticking to expert mode in future.
