Overcure Pretty Useless

[Lyrinn]

I'd like to see it last 30-45 seconds. It'd be potentially much more useful then in primals or otherwise.

Either longer duration or make it instant cast and free like BLM procs. I want to say that might be "OP" but if you use Cure III when it's unneeded (not that you'd get the procs often anyways), you draw a lot of enmity, so there's a clear trade-off there.
