A warrior with about 4k damage probably can deal over 10k damage with critical autoattacks.
Also being able to deal tons of damage does not prove anything. Everything can deal tons of damage in the endgame, because tons of damage is the only matter of character progression.
But it does not change, that physical damage has it far easier to deal tons of damage.
P. S.: Pretty sad that tons of damage is not an exageration in this game...
