energy gathering

[historyboi]

i havnt been playing that long but one of the problems i have is the fact that i cant seem to get energy when i need it or i have plenty laying around when i dont. try to save up energy in a loki frame on a assasination misson and i end up getting to the boss with only 75 energy out of 150(without using any skills). because i am new i have probably missed the reason for the energy drops being the way they are, but wouldnt it be better if energy gain was based more on damage done to enimy hp?

possibly a energy/time + damage done = energy.

this would also make it easier for people to stealth missons by cloaking and taking out a group of 3-4 then recharging on the hostiles that are alone.
