I agree with Modus Vertas topic. Very very good imo.

However I have a problem with the Light Arts suggestion. If you're a good SCH and you love the job (and all aspects of it...not just spamming dark arts) then you will at least have the Surya's Staff +1. If you have leveled WHM as well as SCH and have even more multijob cure potency gear and are primarily a mage chances are you have the Selenian Cap with 3%, Tatsumaki Sitagoromo with 5%, and possibly a Fylgja Torque(+1) with 2%(3%). If you leveled SCH before the the Abyssea craze and did Sea as an event, you'll probably have at LEAST a Korin Obi giving you a 10% boost with Aurorastorm up. ALSO if you've cleared Dynamis Xarcabard that is ANOTHER 10% from the Atma of the Rescuer which will put you at or above 50% if all conditions are met (not including Obi effects since those stack above the cap). SCH has a lot of cure potency through gear/atmas availiable. It takes the player to decide if they're going to go head over heals on their healing magic set and go that far. When if comes to the Selenian Cap and Tatsumaki Sitagoromo augments, any other augments are easily replaceable by new gear except for the cure potency augments which can't be found on any other piece (other than WHM gear) but these so imo they are the prefered augments to chose.

Now as for the OTHER suggestions...other than Cure V which is unessessary because of Rapture, I'd stamp a giant YES on them. Tier 2 weather spells I would assume grant the effect of double weather which would be no less than AMAZING. An tier 2 helixes I'd die for. Seeing my Helixes proc at 500+ damage atm is enough to have me sqealing to myself (and I don't really have pimped gear lol). It'd also be cool if the tier 2s inflicted a bad stat or something like Cryohelix II inflicts mild paralyze or something awesome like that.

The Dark Arts suggestion I agree with sort of. To be honest with atmas, ebullience, and weather procing Obis/Twilight Cape/Zodiac Ring, you can do some pretty dirty damage. And please don't feel gimp for using ebullience. Some SCHs kind of do. Just think of it as a way to take an extra step forward. SE gave us the job ability so use it!! But the fact that we CAN'T use Eradico's Mitts PISSES ME OFF. I'm stuck using Goliard's cuffs because i'm too goddamn lazy to get the +5 MAB mitts off that fly in the past. If I could just wear those oh my god...

Fusion spells look really cool. The teir II ones I believe would be enough because you can string those together to make a level 3 SC fine.

Great ideas. I hope Squeenix considers some of them.
