Wargames might hurt this bracket if overdone (everyday or multiple times a week). That's something atm that's nice about this bracket, the competitive games aren't forced. They're simply pugs facing pugs with a group thrown in here or there sometimes.
Every 10v10 I've seen or been apart of has been the same. Sit 30+ min to form, druid grabs, teams sit mid for stacks, stealthies burst efc at like 2573 stacks, a team loses, people ragequit or just give up.
I can't speak for everyone, and the amount of people who sign up for this might prove me wrong, but I'd prefer not to take the risk and burn people out.
