7 didn't really have jobs, but the Blue Magic system I was planning to use was 7's, since to my mind it's actually pretty simple. Get hit by an attack and survive, learn to execute the same attack, easy right? Given that this is a narrative combat RP, that means taking any technique head on without defending will actually do quite a bit of damage, so I think it's a fair trade off in the long term. The only real trick will be surviving the fight after getting hit like that.
