Small suggestion/request for SMN

[BillyKaplan]

NOTICE: This is in the hopes that it won't be long before we see the job get an overhaul and is meant as a temporary band-aid

tl;dr Reduce Ruin III's MP cost and give us a trait that replaces Ruin with it.

Between the nerf to III's potency and the minor buff to I's, there's absolutely nothing justifying the absurd, inflated mp cost to Ruin III. Ruin IV makes it all the more absurd because that lovely skill has a drastically lesser mp cost too (even if, yes, I'm aware, it's locked behind a proc).

Most SMNs I've seen spam Ruin III anyway just to try and make up for damage we lost elsewhere, but that means our MP drops because that skill wasn't meant to be spammed outside of Dreadwyrm Trance. Other than being an annoyance, it can also hinder our utility to help with raising, as well as serve as mana batteries. Admittedly that one's better left to the BLMs (only real utility they have an advantage in, I feel) but in a pinch, you do what you gotta do.
