And the guild leader can just kick you and replace you with someone who wants to do it.
You have a choice too. Find a guild where it's not important to its leaders. Several emerged on the ps4 created by top players who don't want to deal with it. If you feel like you should stay in a bracket 1 guild then get better or join one that is better. That's what it comes down to.
Edit: 2 other things. 1, I was in a guild that didn't care much about gw and I found it frustrating so I left for 1 that did. 2, this isn't meant to be overly critical of you. The average idea really just isn't a good idea but as mentioned, maybe count the top x scores has been mentioned before. That's not a bad idea. But if you want to win, you really should find ways to do better as a guild first as well as yourself. Gra, Nemesis, Quimby, DoVelho. 4 off the top of my head who showed big gains since things started. It does happen.
