have to disagree on this. in the end its not your guild and the leader/s can set whatever rules they want. personally we have this in my guild aswell. because we dont wont heaps of people joining and then not chatting/contributing to the guild. im easy though i only need one guild and i am happy.
they can set the rules...I never said they couldn't. I did say it makes them creepy controlling weirdos who need to grow up.
Maybe because people are tired of guild leaders with Napoleon complexes who attempt to exert control over the lives of others through their position as guild leader? That system has been tried and failed. Many people are fed up with the control freak guild leaders who create a guild for the personal sense of power it grants them rather than making the effort to build a community supportive of their membership. I'm not saying this describes you personally as a guild leader nor does it describe every guild. However, it describes enough guilds that ArenaNet saw fit to implement the multi-guild feature and give control to the guild membership rather than to the guild leaders.
It's a welcome change and frankly nobody's business which guild(s) anybody joins or who they represent. Successful guilds will embrace this change and focus their efforts on building the best possible community that is supportive of their members rather than attempting to exert dictatorial control over them. If you make it worthwhile for people to be in your guild, they will be more likely to stay and represent it. Any attempt to restrict them will quite possibly result in lost members as they opt to join less restrictive guilds. As the old saying goes, "You catch more flies with a teaspoon of honey than with a cup of vinegar."
