As soon as I start a casual PvP match my difficulty resets to Warlord 4.
All my casual PvP enemies have 150+ health, 100+ Armor & 80+ Damage.
I have just changed my difficulty to Normal, Hard & all 3 other Warlord levels but it makes no difference & as soon as I exit the PvP (either escaping or winning) my difficulty has reverted to warlord 4.
This is a real pain for getting this weeks snotstones.
