Empowered Champs
Those who said ' it won't affect me - well it might, empowered are already in G4, I've just seen the strongest so far, Arbiter +2, Krisk +2, Candaphron +2 and Ma'ashalled +1, as the bots (sorry weaker teams) are being slowly removed this power creep will continue and those folk who can't do arena/great hall missions will find it even harder to progress
