If all of this stuff SCH main has is so useless, and it's Cure V you're wanting, play WHM?
I said all the stuff SCH has is useless? My only complaint in regards to that is Libra/Animus and you're damn well deluded if you think either make SCH worth crap. I actually like having to use Stratagems for spells and being able to switch between two rolls, I only bring up things like Stratagems wasting a couple seconds to use is because that is what balances the job out to some degree.
You must be seriously be lacking in the ability to read because I've said numerous times that SCH Cure V wouldn't be anything like WHM Cure V. I wont level WHM, why? Because I don't want to stand there casting "Cure V > Cure VI > Cure V > etc." for the rest of my days. SCH main healing is far more entertaining for me, I simply demand Cure V because relying on Quick-Magic to proc when the shit hits the fan is completely stupid.

Again, giving SCH cure V and striping the fixed enmity on it isn't going to fix SCH at all. It will just make it more like WHM, and then you will really have something to complain about as far as pulling hate.
I'm already complaining about hate. WHM gains zero enmity. BLM can wipe its clean. DDs can all tank. I guess SE sees it as ironic that the one job that's meant to control enmity (even though THF does a better job of it) is the only one left that still has any hate gaining issues. But that's a digression, the point is SCH with Cure V wouldn't be anything like WHM. We'd be spamming Cure IV with the occasional Cure V while having to watch our hate, where as WHM spams Cure V/VI with zero concerns.
As for fixing SCH, I really don't know what to say. You say SCH is broken, which means you admit it's not doing it's role properly. Then you go ahead and say Cure V would just make it more like WHM (which it really wouldn't)? You are aware that Light Arts it meant to make SCH act as a WHM, right? You're either a complete idiot or you've had a massive lapse in cognitive ability recently.

And I guess I need to go tell my SCH friends they're doing it wrong as /WHM for healing. Huh.
No. You're wrong for saying SCH subs WHM for Light Arts, it doesn't. WHM is an irrelevant subjob the moment Lv.99 comes about, right now it's a reasonable subjob for Haste, but thats about it. Though if your SCH friends (and really, go run that Rapture on a 3 minute cool down idea by them, or better yet send them here, they might actually know wtf they're talking about) are in a party with either a RDM or WHM, /WHM becomes completely redundant because they don't need to cast Haste.

Honestly, I really don't know what else I can say about Cure V. You just don't want SCH to have it, that much is clear. Any WHM with an ounce of understanding of their job would realize that giving Cure V away with proper hate gain doesn't threaten them in the slightest. WHM can spam Cure V/VI until the cows come home. SCH could get off maybe six Cure Vs off before drawing unwanted attention. It's damn near the epitome of balance. Every single person who's said no to SCH getting Cure V has been completely incapable of countering this argument and you seem to be no different, don't bother saying "Just give SCH a HOT spell". For one I hate the acronym and for another its not an argument against getting Cure V at all.
