Don't care about that really. Not when it takes a minute to bring down a wall and another minute to make 3 to 4 scout attacks to find a very good target.
IMHO is all a question of having pride of the guild where you currently are. Also at the moment I do give more importance to guild than to individuals. One thing is you raidind i.e. lelipot12345 another is you to raid i.e. lelipot12345 [FUN] guild member.
Probably GREE will not allow name changes for free, but IMHO that's to bad. Surely they don't profit a lot from it, why giving players a small RPG extra.
