I don't think anyone would willingly trade for something that nerfed their points, loot, tokens, etc. during an event.
However it might be worth considering a crafted trade-friendly Energy that is balanced against Platinum cost for energy refills. This would definitely mean a higher number of essences, a longer crafting period and a much higher gold cost.
TBH I am not very confident that something like that would be a good idea for players and Spacetime alike - but we will discuss it :-)
