Having the shield being at least the same as an AST shield is good, because it means we can shield (t least) as good as the other shield class.
Faster summon is always appreciated so we dont waste swiftcast if our pets dies (not an usual thing)
Ive never had much of an MP issue but its always nice for Adlo to be cheaper.
Sustain is very welcome, it was a stupid thing to take it away, specially for a SMN

Anyway I cleared O4S before the patch and after the patch, SCH has always being a good job, and capable of clearing all of the games content, as every other job.
