I can see where you're coming from...but personally I don't care about the power of guilds, and neither do my friends. We group up for fun when we have a chance. So from my viewpoint powerful guilds wouldn't really matter, what matters is me being able to group with their high levels (NOTE: though they have created low level character to group with me for the time being ).
Oh well, it's moot anyways since they probably won't allow it anyways, just really don't see why guild power matters.
