• Difficulties are still applying stat buffs in PVP + Arena but not rewards. Status: We have reverted them back similar to the way they were working in 1.0.8. (apart from the fact that the AI Combo Breaker will gradually turn itself off in ALL difficulties now). They will be changing to the way we intended them to be in patch 2.0.
