Just noticed that in unrated PvP , my versatility can go up to 51% and speed up to 17% (no potions, just buffs from mark of the wild and armour enchants).
But in rated play , my speed gets capped to 11% and versatility is capped at 50% with the same buffs.
The 4 set and 6 set only work in world pvp, but for some reason the 2 set has always worked in unrated battlegrounds. its a very small amount, but probably enough to make obamna’s character sheet show 50% instead of 51%
