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.
I play whatever I'm in the mood for, don't really gravitate towards a specific play style. Although I do tend to like DOT/poison builds.
In MMOs I tend to have at least one high level tank or healer. I like being able to hold the group together. In TTRPGs I always pick my class last so I can fill in whatever the group needs.
