That’s a decision you suggested to people who want to PvE a few hours ago…
Also, it’s my personal opinion, but right now guild is a property of Guild Leader, because he is the one who created it. And I think it’s the right way of doing things.
If you disagree with the leader, then just leave the guild and create your own with your friends. There would definitely be PvP focused builds that will always or almost always accept those “friendly wars” and participate in GvG events for glory and rewards.
But let those people in a guild who don’t want war live in piece. Leader should decide the way the guild goes, not regular players. That’s the reason why he is here.
