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.
in a single player RPG I'm a basic ass heavy armor tank with as much social skill as the game allows for. in an MMO I'm basically any form of utility, I like the extra thought that goes into being a tank or healer. dps tends to have a clear correct way to hit your buttons in every encounter in the entire game and the better you are at hitting your buttons exactly that way the better a dps you are. but tank and healer can have a slightly more nuanced thought process involving risk and reward and whatnot
