So I just started my second character, a light side consuler, after playing through with a dark side sentinel. I have to say, I can't imagine going through the entire game without at least one offensive aoe. So is it worth it to put the points into Force Storm as a light side character, or will it just eat up my FP too quickly to be useful? I know as my sentinel, I never had any problems with FPs after around level 13 or so, but I didn't have any cross class powers, either.
