Having leveled both BLM and SCH I see some interesting points here, however SCH was a very powerful job at level 75. To powerful, and personally I think the B+ skill in elemental magic is hurting the job past level 75. As for Cure 5 I'm not sure I'm for it personally. Its not that it's a bad idea it's just that I don't see how it separates us from WHM or RDM or BLM.

I think new helixes or fixing current helixes is needed and new spells that makes SCH stand out from BLM and WHM. And lastly I think they need to raise the number of stratagems as well. SCH gets T5 nukes, so I personally feel its fine when doing spike damage.
