Yeah, I gotta go with pure roleplaying aspects of geasa rather than minmaxing the limits out of it. I had the first gaes requested in my campaign happen yesterday, after almost a year of game time - I asked what the guy wanted (after jokingly suggested "must be on fire") and he said "Must be in the presence of fire". I took it - so he's going to carry around a zippo. Of course, if he's in the dark and needs a fire he could always use that flamethrower spell...which opens him up to ease of targetting...but it's all roleplaying - he's a pyromaniac at heart (Yes, Halloweener, likes filming nice explosions, that sort of thing).
*shrug* Toturi, stop playing with your food already.

Edit: Oh Lina, don't think I didn't catch that remark of yours.
