When the game starts for real, do you think that because a user can have more than one char....
It may help ppl to spy on different guilds i.e you have two or more different chars with different guilds playing them off each other.

That way you may get info about planned attacks and tradings etc

Nothing new about this, we used to have opposing colour characters who used to 'steal' the flag and hide it. Kind of an 'Anti-Capper' spying on the other colours too.

Hehe, not to mention joining guilds to find out where people are...lol but these things happen, and are delt with by guild members (and stuff like that is human nature, so bound to happen in game too...)...

Not a bug, a feature =D
