Yes, this is another crying post about TW matchmaking. Our Guild's power is 256mil and all 50 players participate in TW (in almost every TW). We are facing 296mil GP guild and have 21 squad per zone....
Not necessarily. It is very unlikely to happen at lower GPs but not excluded and probably difference is not that high. More like 260m vs 250m at full 50 on both sides (not 411m vs 340m that can still happen at full 50).
