I agree with Emoe and Husanak on this and have been a proponent. My system would not be a high drain per power it would be tier and skill point dependant. If I am specced into tractor beams and I use TB3 I would have a less aux drain then say someone that is partially specced in TB, and lot less drain then someone not specced in TB at all. I think a 5 7 9 normalized drain would be a good start each number representative of if you are not specced into a skill and 1 2 3 scale if fully specced into said skill. So being fully specced would not 3 aux off the drain of a level 3 skill. The principle being even though the drain would be higher the efficiency of the skill would be higher for being dully specced so a TB3 would have a fully specced drain of 6 aux.

Another thing I would be in favor of which I think is a compromise is make skills dependent on aux would rely on the current aux levels so if a skill runs for 15 seconds its strength would vary as lets say an aux battery drains off. So lets usee hazards. You are flying an escort and you are taking damage and you use an aux battery to get aux to 100 and then hit HE, the first pulse would be at 100 aux but lets say the next pulse the aux falls to 95 and so on and so forth. Right now most skills rely on the aux level at the time of trigger.
