Quote honestly, being good at EverQuest required not pissing yourself or hopefully not having to move your character while running down to get the pizza you just ordered, combined with a ton of time with nothing else to do. Did you play Vanilla EQ? Skillsets were not existent or minimal at best. The only skill you had to learn was making sure you didn't pull other camps mobs, don't hit the 2-3 mezzed mobs, which later turned to massive AE groups anyway, and when on a raid, hit your defensive as a warrior or make sure everyone has their A$ resist gear.
Seriously, that's it.
There were plenty posts here around the SoL boss days when the entire fight mechanic was making sure people weren't falling asleep while fighting in a corner or didn;t get too distracted by a new episode of 24.
Edit: Echoing Mkopec1 on this was up to about Planes of Power when I quit. I am guessing they have actual boss mechanics now besides hoping CT didn't call your name.
