Seems like you have some internal guild training to do. You might want to get on that before the next round.
Rogue flags are no abuse, they're merely an annoyance. A really big one for you, apparently. Regardless, they've given the needed control over the spending of treasury goods for buildings, as they gave control over opening upper levels of GE for the same reason. Planting a flag costs the guild treasury nothing, so there need be no control.
Yes, I understand you're asking for controls to make your job easier. I don't want your job to be easier. I want your ability to lead effectively, or not lead effectively to be one of the many differentiators that will determine the success of your guild on the battlefield. Step up, or don't. Succeed, or don't. That, my friend, is part of the game.
Why are you asking about GvG? What you can or cannot do in GvG should have no bearing on GbG. Don't know why those tools are there in GvG, don't care why those tools are there in GvG. All I know is they're there in GvG, and not here in GbG. I like it better this way. It now forces you to gain consensus from your members and not just lock them down to play the only game you'll allow. No more, your way or the highway. That leadership style simply won't cut it in GbG.
It just may be that you are not cut out to lead in GbG. If that's the case, a smart guild leader will turn over the task of leading GbG to someone else in the guild who can actually lead a team who willingly follows them without controls or restrictions.
You keep calling yourself a leader, yet you don't actually want to lead, you want to control. You don't need tools to lead.
If you have confused players, educate them. That's what actual leaders do. Your ability to do this successfully or not will determine your success in Battlegrounds, or not.
I only play on PC and in almost 2 years of playing, I've never touched GvG and have no plans to. Much of the reason is the 'show up and throw up' mindless nature of it. So, there goes that argument.
In my guild right now, attack decisions are being made by consensus with no 'key strategists.' We all have a voice, we all have a vote, and we all work together as a team. Not because we have to, or are forced to, but because we want to. Maybe that's the core issue? No, 'I' in team?
