>>713875062 (OP)Tanks and healers only exist through contrived means, Aggro specifically, in a very specific model of slow attrition focused combat. Without the several contrivances, the trinity can not exist.
They are fundamentally bad game design, the equivalent of Parrying diminishing an action game to an absolute trivial base. It's so bad that MMOs have to put in fucking jumping puzzles, minigames, and AOE dodging nonsense for their staged fights to make it not soul crushingly boring.
Healing should be a group effort, something that classes like wizards and rangers do on the side while they're sniping and dropping fireballs on key targets.
"Tanking" should involve formation tactics with many of the frontline fighting classes physically blocking enemies approaching the squishier classes, cycling in fresh fighters while the injured step back towards the wizards/rangers.
