And they don’t leave.
Some will be camping your corpse. Others are camping the quest objective in stealth or packs. Others are camping the damn Spirit Healer in case you try to respawn there.
Warmode is a great mechanic. The players who live there are split evenly between honorable combatants who enjoy the thrill of fighting an actual player and not a scripted AI, and screeching inbred basement gremlins who’d explode into flames if they ever came into contact with grass.
Until Blizzard can fix the Sharding and/or the population imbalance, there’s no point for us to engage in Warmode because we’re going to lose more time being ragdolled and waiting for our resurrection cooldowns than we do to actually play.
