I occasionally pass a spark to the tank, or to the cleric if he has BB on, but I really don't know... Is there a way I can see who needs a spark? Or do I pass it as soon as I have it? Or, is it common that ppl ask for chi? I've had the latter one a few times and this is easy, but usually noone says anything, not even a thanks if I passed all my sparks as soon as I get them. What's the most reasonable approach here? And are there situations where I keep my spark (or my two sparks) to deal more damage?
