I'm in a guild of 48 and we started tier 4 yesterday morning.
32/48 have hit as the others either don't bother or await phase two which is far easier. All this raid has done for officers and leaders is highlight those who aren't putting in the effort but then again, with the woeful rewards and annoying mechanics, it's hard to get too frustrated.
Look forward to the raid gear improvements but sadly the damage has been done. Motivating members daily has become a chore.
Fingers crossed the rewards outweigh the dull nature and we can get back to working as a guild again.
