obviously I can and I have done several times - layer hopping to avoid PvP was always considered an exploit in WoW Classic, it always
it’s extremely problematic no longer be able to punish people as we see fit, this was one of the main positive aspects of this game.
corpse walking was introduced in game design for a reason, additional time when you keep dying was also introduced in the game design for a reason, when someone last resort is to use the spirit healer to resurrect they are imposed a debuff and also extra cost to repair… and layer switching to avoid all of the above IS an exploit, no one is being invite to play with a friend, they are being invited because they are weak and they know I cannot guess which layer they went.
