Consern is that only the top guilds will run 40 man raids and aLOT of people will not be able to raid. Cause its going to be difficult to find 40 people that wants to log and raid 4-5 or 3 nights aweek. But i hope its a success. It was awesome raiding back in vanilla/tbc. I am still raiding today but 10 man now. There are way more 10 man guilds then 25 man in wow cause of the effort it takes to get people online and beeing active etc etc. I seriosly cant wait for this game it looks awesome! Cant wait to get to raid 40 man again if i find a guild.
