Give Reds the ability to grant physical and/or magical shield effect that doesn't stack with each other and lasts for 5 seconds with a high mp cost - to help negate severely damaging TP moves to a tank or himself.
Not so OP because timing and player skill is crucial.
The only way enspells are gonna be better at this point is if Reds have an ability to increase the potency or duration of a particular de-buff associated with an en-spell element. For example Slow II or Paralyze II staying 'sticked' with Enstone or EnBlizzard, aside from that lolrdmmeleestopitgtfokthx.
What of the issue of Red's barspells? Is it the Dev's vision to see a Red barelement himself and his party wipes from an elemental explosion and the only one left standing is a Red? So that he can chainspell raise everybody just so that they can get mpk-ed again and see how useless it was inviting a Red for party support?
I don't know what other Enfeebling spells are in the works but I'm certain it won't be anything nearly as effective as an exclusive RDM stun effect spell based off Enfeebling magic.
I'd be all for just deleting the job if it wasn't for the fact that it's a good sub.
