Perhaps my experiences are more "kick down the door" fighty-heavy dungeon exploring escapades than your games, but IME figments and images frequently won't solve an imminent problem, without you having failed as an illusionist.
In any case, I really like the ScM and its write-up, especially the notion of someone who's gone slightly insane and no longer can distinguish reality from illusion. My last ScM simply preferred simulation to the real thing. Whether it be a sumptious feast or...use your imagination...
