hmm they sound nice, for the none job-specific rolls i would say:

Bolters: movement speed + & sneak and invisible
Casters: fast cast & MP cost -10%
Coursers: snapshot & ranged attack +
Blitzers: not too sure what could go with weapon delay -, i'll add it when i think of something
Tacticians: regain & weapon skill or skillchain damage +
Allies: enhances skillchain accuracy and damage & occasionally double damage of level 1 and 2 skillchains (could be too broken if implemented with light and darkness, where you would only get the normal 11 bonus) (this was all i could think of for somthing to go with skillchain damage and accuracy)
