Sorcerer tank

Perhaps not the most optimal tanks Sorcerers can still handle themselves in many situations using their gravitational and time magic for defensive purposes, particularly against ranged targets where they can set up time slowing barriers to allow them the extra moments to magically deflect or avoid incoming projectiles or magical damage combined with their own wide range but weak area of effect spells to hold agro from the enemies around.

Pretty much defenseless when enemies comes too close a Sorcerer will go down quickly if no one takes care of the melee enemies in range of his threat building area.

Sorcerers have skills such as time slow which will help them avoid almost any incoming projectile, time stop to stop incoming projectiles, counter spells, spell interrupt and spell steal to hinder ranged casters from completing their spells and the ability to change the gravitational pull to disrupt any attack coming their way.
