There is a contrast however. If you are paralyzed and you cannot use a spell, you recast timer is not reset. If it is a job ability it is reset.
I think it would be better if items were treated like spells instead of job abilities.
I think it would be better if JA's worked spells to.

The worst one I can think of is Call Beast :P there are plenty of times when a bst NEEDS to summon a new pet.. paralyze on that move means death. Charm was only 12s... Call Beast is 4:10 w/ full merits.

4 minutes in a fight where you are 50% power at best.
