I HAVE AN IDEA: why not input a teleporting device for guild to use in pvp so that if their guild is their they can summon other guild members. but to control the use of everyone using it only a certain ranked or higher member like a commander can use this. tweaking this idea with other features could be useful to you for the game so please do with it as you will.

Wow, that is hard to read. I would suggest sticking with the original font.

Anyway, I don't like the sound of this. Just mass teleporting a guild to a certain location would be way to over-powered. I think the system they have right now is pretty good. You can teleport to a Wayshrine in the area, but you can be cut off if the other faction is smart. It brings more tactics than just "All right, our guild leader is going to jump into the middle of 'em and he's gonna teleport us there."
