That makes sense. Yes, it does get very confusing. In that case it's better to hold on to dead weight just in case they pick up a win or two and make adjustments after the war.
All you need is a Clan size of 3 members or more before the roster lock, and you'll be automatically enrolled in BR-PL.
Thanks for the backup on that. (edit): Nevermind, I thought I was in a different thread, lol. Anyway, thanks in advance for a future backup.
