I think it would be a good invention if Guild Members could divide into 2 groups and battle each other in the guild hall, training PvP skills. To have a bigger success in defeating opponent guilds.
Like for example henchmen on the both sides of the Guild Hall. And 2 groups of guild members PvP each other. If they want to go GvG they can always start it by going Guild Battle.

actually, i was hoping for something like this too. i think it would be a great way to practice against specific skills. like a "training" mode.

I was hoping just for a scrimmage/minor (2v2/3v3/1v1/4v4) area in the guild hall. That way you can compete with team-members, work out builds, and just have some fun with allies. It's not always true in the other arenas. In competition arenas you can't choose your teammates so you might end up fighting your guild member or not even being in the same match. In team arena competition runs rather wild and if you're just trying out something with a friend then it'll be hard with the organized people. I probably don't need to mention HOH, not much point there.
