[Snake]

Death Knighting should be a Main Class only skill.

Aside Death Knighting being a giant all-stats buff, which is already giving an enormous advantage to the user, the passive 'Fallcall' combined with Ghost's Ether Invitation does 1000 damage to any race but Shaitan, and effectively one-shotting people for an easily-inflicted status effect, Fear.

(And Fear can be inflicted in many different ways without counterplay, be it with the Haunted Soul, Haunting on a Claret Call enemy or using the Hexer's magic, Fleeing Spectres, on an enemy under Payback.)
