Booster Energy drain Reduction?

Could we maybe possibly get a booster energy drain reduction??? Make it like weapons so common is obviously the cheapest but rare and epic cost the same???

Selfish request I know but I just wanna see what other people think about it.

they nerfed it in the past due to issues with i think some cabins.
cause people would just load their builds with it and go ham on anyone they could. i think it was really overpowered on the tusk cabin but im not sure. i forget why they nerfed the energy cost.
