If we assume players are at same lvl of you (not skull lvl like raid boss), then there will be no avoidance in pvp
but, if your class have some sort of avoidance from skills (tank spec especially), I think you still be able to avoid some hits
they said anything about it to a pvp perspective, so this is just my 2cents
Don't make funny of me, If you don't understand what I said.
I'm just a guy with poor studies, that don't have english as first language
Dodge and parry will be 25% lower which on most will be about 5% less avoidance. On top of this you will be getting 12% exp baseline. Combine those and avoidance in pvp will be very low not gone but very low.
Most classes right now have between 23%-28% with str classes being the highest which makes no sense but anyway. Wod will cut that by 17% for end expansion and at the start most had 14-18% so we're looking at people having 0%-11% through wod.
But sadly none of this is happening because they wanted to make pvp better its just pvp getting pve's leftovers as usual.
