It's actually quite sad to see. The people I know that moved to a large guild don't really seem to like it. One hasn't logged in weeks and told me he regretted leaving and now lost so much renown it's not worth trying to revive his guild. LFMs are down significantly. One person that used to lead a lot of PUGS moved to a big guild and no longer does.
The people hurting most are the casual players that aren't desired by the guilds that have their own organized raids. The vets in their guilds "saw the light" and moved to a big established guild to get out decay hell. The guilds the vets go to never wanted and still don't want the casuals. So it's really a consolidation of vets to the big established guilds.
This is what happens when you create an imbalance. It's playing out differently than I first expected, but not for the better.
Perhaps this is what Turbine wanted. A consolidation of the vets to a few big established guilds and a the rest get left behind.
Being in a small guild doesn't mean you don't have friends. Is it necessary to throw at least one insult in with every post?
