I predicted this would happen right when guild perks were first introduced. I believe I said it in a comment on here. Just like what happened with gearscore, people are caught in a catch-22 with their guilds, unable to get new members unless they have leveled up, levelling up requiring new members.

Guild perks seem like a good idea on paper, but the fact that they were implemented in their current state shows that Blizzard have lost touch with gamers. First the Diablo 3 always-on fiasco, and now guild perks acting as a barrier, not a helping hand, it seems that Blizz have gone too long without an actual gamer at the helm.

It may seem like blasphemy to some, but Blizzard need someone new leading them. They have spend too long at the top and they can't predict player response any more. Perks should have been scrapped from day one. Early on, sure, they were fine, but as time has passed, players have become more snobby towards lower level guilds.

I like the guild achievement system, but IMHO it should be cosmetic only. No rewards. No perks. At the most, perks should give mounts and vanity pets. Not heirlooms.
