Why nerf Mages and Hunters so quickly, but allow Druid and Warlock to be so OP in PVP?

Paladin also globals people so nerf that
Rogue saber slash puts a gigantic bleed on you so kill that
Mages can still pop you in a couple seconds so delete that
Hunters as well so nerf em again
Shaman can global you needs to be removed
Priest penance is too mama efficient and powerful for sustaining so cut that down
Druid can cast sunfire in cat and erm yeah delete

Season of whining lol.
