I actually play on a low pop / no queue server so i say this with neutrality (I rolled from shaz to mograine to stonespire), increase the layering to whatever the hell removes anything more than a 1 hour queue time.
I say this in full knowledge layering is supposed to be removed at some point. However in any project management situation, you’re looking for control. Right now blizzard have seemingly no control over the enormous influx of players. Buy yourselves time, YOU are the ones who decide when P2 and layering is removed. Give yourselves an opportunity to provide a solution, via free transfers or whatever else you can dream up. Right now you’re at risk of losing an enormous opportunity, thousands must feel like quitting and playing something else. Open the doors, take them in, let them level, some will get bored anyway and when you have stable numbers - strategise on the best approach to removing layers.
Players want to play - let them!
