Watch what happens to any guild that forces geared players to go back to early raids that they need nothing from as AQ40 and especially naxx release.
The best part of naxx is that guild need more tanks than before, so all the bad guilds lose their best raiders and collapse. It is kinda hilarious every time.
But yeah, let’s force our top healers to run MC for the 30th time so our offtank can get a thunderfury - that’s gonna workout great.
