At 75 our gear selection was attrocious, unless you had a busy shell that did events, but we've been getting a by far increased amount of easily accessible gear that benefits a SMN.

If you're refering to melee gear:

No offense, but of course it's limited we're mages. We're in the exact same boat as all the other backliners looking to melee, no better no worse. Count yourself lucky there are any melee armors for mages at all, and make do with whats available.
Mainly referring to our armors always being too situational. We have no armors with -perp -BP timer -enmity +skill +MP +hMP +avatar stat +random job specific boost. The job has 12 slots, and I carry 60 armors. If we just got decent hybrid armors with all important stats, we'd probably do fine with about 20 armors. 30 armors, if you need melee stats also.
