Through my years of mmo and rpg gaming I've tended to swing between the two extremes of the warrior/wizard dynamic.
Some days I just want to be a dumb tank in full armor soaking up hits and acting as a wall for squishier classes. But then there's days where I love being a glass cannon that can kill something in 1-2 nukes but a strong breeze can kill me.
The least fun I've head with a class was as a healer druid in Everquest. Something so stressful about the party relying on you for heals and if you wipe it's generally your fault. idk how people dedicate themselves to a class like that.
Fast melee. Don't have to learn any magic system bullshit, and the game is typically designed around using melee weapons. Lots of games have slow hard-hitting weapons that are just too slow to be viable, but if it's possible I do enjoy me some caveman ungabunga hit with big stick from time to time.
