that is the thing though, its in the attempt that people would build a well rounded raid and stop building it for themselves. If the group is 15members 7 of them mages, and the next 10 players know they will have less chance of their gear dropping. there is a good chance that they WONT join, and thus the raid wont be able to be completed, forcing the raid leader to build a balanced raid so that people will perticipate and have an equal chance at gear
please think of things like this before you post stupid post, thinking your a genius
