This game needs new Tanks. Soon

Move survival back to ranged and give a 4th spec to be hunter melee/tank, I’d tank.

the problem is not how many classes are for tanking, the problem is people don’t want to tank, they want to DPS, and there is no real incentive for tanking, getting extra money? or the bag with enhancement stone in it is not enough for people want to tank, so even if you do another class avaible to tank, people will still use the dps one, because they don’t want the responsibility of ruining the raid, or mythic

This is correct.
Arbiter utilized a buff to enhance their armor, and then relied upon a regenerating frost bubble spell which absorbed a percentage of the damage.
The time slowing abilities weren’t really used so much as they used debuffs on the enemy to reduce damage intake.
They also had a clone ability iirc.

Nope, it needs to do what hasn’t been done since inception, add a dps caster.

This needs to happen.
