I decided to make a formal suggestion here for the devs- as practically all of the players I see agree that the phases need to be longer. I see most say 1-2 months longer per phase, bare minimum, for a total of 3-4 months for each phase. (source thread; https://octowow.st/forum/viewtopic.php?t=472&start=10)
However, I would like to add on to this. I believe the team should do small custom content patches to existing zones (planned by Turtle) to maintain the excitement during the phases; Dun Morogh, Stromgarde, Tirisfal Uplands, Blasted Lands. It could start with small and focused patches, adding a few new quests, NPCs, subzones, etc.
