After tiet gear doesn’t matter. But pre raid i’ve been thinking. The classes listed above could benefit more being more tanky.
Warriors wearing leather, warlocks full glass cannon, shammy/pala wearing dress…
Then get one tapped by MC elemental Fireball.
For example warlocks could go raid with full t0, all you need to do anyways is to focus on curses and banishrs no matter how much damage sbolt deals
