Justice and Rule

It almost never plays out like that for us. It's almost always a long discussion about whether you can hit three or four targets, not hit allies, not burn up the papers on that desk in the process, etc..
And then the 25% of the time where the answer is "Yes you will hit an ally or that thing you didn't want to burn up" the caster says OK nevermind I will pick another spell. And MORE time is wasted waiting around for that.
Meanwhile the fighter runs in, hits the same target over and over until it goes down, and bobs your uncle.
Yeah, I've never seen martials have much problem figuring out what they are doing. More often you get spellcasters trying to figure out what spell they can use to try and out-think the encounter. Everyone is trying to find something in their repertoire to cut whatever Gordian Knot they think they are facing.
