Patch 8.0 - How long is too long to wait?

[Daralii]

I remember that WoW only managed that because they bought out a nearby studio with 100 developers whose game had collapsed, and before that they were struggling to recruit and had far longer patch gaps than FFXIV.

So if Blizzard needed fewer than 100 new employees from a dying company to fix WoW's cadence, what's stopping SE?
