Many people dislike FC recruitment shouts, tell spam, invitation spam. It would make gaming experience for many players better
I would like to see a board in game where you can use certain keyword to find the FC that fits you best. I would like to see this for raid groups also. I can see this as a board displayed in each citie next to the GC for example
