...and I don't think it's an exploit.
Initially, I thought this was some wild fantasy, but after seeing a YouTube where it was demonstrated and successfully performing it myself on both White Mage and Scholar, it seems legit (and I don't mean that sarcastically).
The thing is, as a healer, you're almost led to discovering this trick. First, you "inexplicably" can't target someone directly with a spell for several seconds after raising (or resurrecting them, as the case may be), but strangely, AoE casts hit just fine. So it seems logical you would eventually discover the "exploit" after getting used to setting up an AoE cure after raising someone sooner or later. Also, when you do time the AoE just right, there is a white and blue "just raised" status icon that appears rather than the red, black, and green weakness icon. So, at least there is an acknowledgement in place that this situation was anticipated. So I'm beginning to think this was an intentional design.
It's cool... but it also bothers me a little.
I've had a tank rage quit on me because I couldn't successfully perform this feat on command, so that's one reason I'm not a fan. It's nice to find a hidden trick, but healers who are just starting out aren't just going to know how to do this without at least some job quest pointing out you can pull this off, and there are no end of abusive jerks who are going to give healers a hard time over not automatically knowing how to do this.
But the other thing that's bad is that if you're raising someone who died in combat... the thing that murdered him or her is still rampaging around trying to add a few notches to that list. Even if you can Swiftcast the raise, you have to deal with dodging AoE and keeping everyone else alive without standing in place waiting to perfectly time that AoE cure so the raised victim doesn't rage with the "indignity" of weakness. It just seems like one more high-pressure expectation that you won't have time to answer for when there's a boss raging around.
So, what do you think of this? Is it an exploit or a hidden trick? Should this be the measure of what separates the good healers from the bad or is this another unrealistic expectation on a demanding role?
