Frost - too much control, too much burst. 14-15k Ice lance spam? 20-26k frost bolts crits? Cone freezes and heroism? Wtf if we wont fix either their amount of control or their burst we will see some terrible glads. Blizzard please do not make the same mistake with season 5. You said at 85 people will go down slower. But guess what with mages at what they are right now it wont happen.
Ferals - too much bleed dmg, too much mitigation in bear form. their dots crit up to 10k on clothies per TICK! They are also can just go bear and hit with maul for good 15k crit. on top of that all their strat is DOT up then run around and watch target getting low. Takes 0 skill to play atm. Please either balance their class around their dots (nerf their DOT dmg). Or atleast make it so when they go bear the DOTs on the target fall off, in order for it to make a fair trade off between going defensive or staying offensive.
