Guild and raid management
This is an aspect where 25s require much more work than 10s. There are solutions which can make a leaders life easier, or solutions which give him a reward for undertaking the chore. There is a fair degree of agreement that raid leaders should get some recognition for the effort and time they put in. Others are worried that singling out the raid leader for extra rewards would simply create jealousy and tear the team apart. I think most players woulf recognise a raid leader does extra work and deserves recogntion.
