or why not give them an ability to go with there race bonus. like if human was able to use an ability that for 50 nrg every 24 hours gain +10% to atk and def.
or ones that refresh your player or npc bt. cutting down cool down is a good one. maybe be the nrg race the lil smerf ppl can have one that lets you have relays on your ship with out losing nrg that would be cool no more uninstalling and no more repair bill from them.
the Konqul can have an ability to remove all traps from your ship every day for 100 nrg kinda like a null fuse
stuff like this i think would be funner then more % bonuses.

^ -1 to this, and +1 to Vekno and Talkens
