I don't think that non-healer raises will be removed, simply because in casual content at least players should have the means to get their healers back up if they're both down. The manner in which it is made available creates a lot of balance issues, however.

The main problem is that you cannot balance utility against DPS, and there is no equivalent utility to having access to an extra raise. These so-called 'raise casters' are perpetually penalized for having access to it, and are treated as prog jobs that you swap out for PCT when you want to meet the DPS check and clear.

The solution is to standardize it as a Ranged DPS role action. If you do this correctly, you will always have the same number of raises. You no longer need to penalize jobs for having access to raise because it's a role effect. There is a very easy lore work around to this:

Phoenix Down (ability): Resurrects target to a weakened state. Charges: 2. Recast: 360s.

You could also adjust the number of available charges to match the fight difficulty, or perhaps even replenish the charges after an Intermission phase or LB3 use. In turn, healers would retain their on-demand access to Raise. I think this is the most fair solution moving forward towards the next expansion.
