I mean if a Feral could do 100k dps in melee, then blink to 30 yards and do 100k dps at range, then the tank dies and you blink back in go bear and tank the boss..... why would you play anything else? They become the most versatile class, useful at every role in an instant. You lost Tranq in most forms for this reason.... and if you got a Cloak of Shadow type spell you could prob raid mythic progression as 20 druids only
Affinities still let you tank for a while, or do mediocre ranged dps for a while but you're not a melee, ranged, healer, tank all in one all the time and thats fair right?
