And how long of a delay, pray tell, is acceptable for you? We are already over two months from the first content patch release for MoP and Legion. Hell we are 3 months from 6.2 and WoD was notorious for having little to do. I'm happy to give them a two and a half month delay as it happened with FFXIV as well, but we don't even have an ETA for the PTR beside Blizzard Soon.
Did they? You sure they weren't staggered till months into the expansion? Were they open at release?
