Paladins oath stance it is long over due.

This conversation proceeds on existing skills, since the OP think that there are existing flaws.

Do the tanks jobs have two existing stun abilities ?

Only because the OP is extremely impatient and doesn't want to wait for 3.0. With new skills in 3.0, there's no reason they couldn't introduce new stuns.

EDIT: Alternately, WHM got a new QoL ability. Why can't the tanks? Or, y'know, wait for 3.0 like sensible people.
