Skills are ridiculously boosted when used as Subjob!
This is as my WHM under Dark Arts:
Elemental And Dark Skill got boosted from 101 to 246!
Making it a C+ish rating!
Then I tried it as THF/SCH under light arts:
Got 246 on all enhancements for Light arts!
Apparently this has been going for a while, but I just noticed it today. Not complaining or anything but its really amazing that SE has just let this go. All this started when I wondered why my Aspir was better on /sch than as /blm....
