Black Monks :
I think a lot of players in guilds with 25 members got tired of constantly drawing guilds with 15 and thus being forced to sit out 10 of their guild. Other ways around this, but they at least have good intentions and are trying to address a real issue.
For once, I find myself agreeing with BM. It was really annoying being in a really active guild of 20 to 25 players, all of whom play both GC games and want the cash, only to be drawn against guild of 12, 14, 18 etc. It just felt unfair to have to leave people out all the time. We had one guy rejoin the guild I was in and he didn't get a challenge for well over a week cos of all the low number guilds and he didn't have enough fans. He was a really good player and he left.
I think the move is a positive one in the long term as it will force short-numbered guilds to merge.
Totally agree that something needs to be done about making recruitment easier though.
