So Im trying to figure out the best tanking classes for the Kaladim server at this point. Are monks a viable choice?
Depends on what you are wanting to do. Guardians are your best raid Main tanks, Shadow Knights are the best at soloing, but every tank can tank 99% of the content in the game.
If the mobs hit even remotely hard, no. Guardians are the first tank with an actual temp rotation available to them.
