Mass has always been extremely FP/Momentum efficient, to the point where it borders on obscene. I would also like to see a drawback to it, given that it provides range, multi-targeting, net FP gain, and several turns worth of momentum saved. A steep FP hike on whatever comes after it seems like a reasonable idea, but I'm sure there's also routes that could be taken involving cooldowns or gimped effects for spells turned AoE.
