Dear Square Enix,
I would like to take this moment to not-so-politely "thank you" for taking a very useful job ability that augments a unique set of spells and made it completely worthless. I get that you thought it was overpowered when it was first released and you wanted to balance things a little. What you did was pretty much destroy it, as soon as Abyssea was released Modus Veritas because pretty much an after thought seeing as how it either misses 95% of the time or is completely ineffective against the rest of the mobs there. Or in the case of burn parties, by the time they're done casting the mob is dead.
Seriously, what the hell is the point of having this ability, and merit categories to further enhance it and the spells is effects, if it's meaningless to use in the first place? You know you could have done something different like say not allow the ability to be stacked upon one another. Isn't that one of the things that caught your eye? A whole bunch of SCH running around helixing and then cranking out the damage with this ability? Well you know you could have easily fixed it by making it non-stack-able instead of making it completely worthless!
Do you know how little SCH are used as it is? Do you have any idea how low on the pole they've fallen compared to BLM and WHM and now you've taken away one of their most potent abilities. So they're never asked, or allowed, to main heal as long as there is at least one WHM present since they have more potent curing spells. They're never asked, or allowed, to nuke as long as there are BLM around since they lack -ga spells and ancient magic making their proc'ing ability laughable at best. Hell I've seen some parties take BLU over SCH for nuking.
You need to go back and revisit this friggin JA and really take a long hard look at how messed up it is. Are you seriously worried about it breaking the game? Even before it was 'fixed' there were, and still are now, a lot more things that are more potent and breaking than Modus Veritas. SCH get no relics, their mythic is like every other one and not even worth 1/8th of the effort that's needed to get it and their Emperian weapon is hardly unique since it's shared with other MP heavy classes.
I'm not saying that the job class has no use, and I know a few others that play the job very well. But aside from pissing of RDMs by Accessioning Phalanx and Stoneskin, storms are about all they have left when you take away the helixes. So that's what you get, a bunch of SCH all diddly farting around on Light Arts because you nerfed their damn nuking abilities. Revisit the friggin ability, we're not 75 anymore and A LOT of the stuff that you've given us since then is a lot more potent and dangerous. Give SCH their dignity back, that's all I ask.
