New Why differing energy uses in bouquet duels?

[MFRavenhawk]

Ok, I get the fact that the differences in the bouquet duels from previous years is a resolved bug....that meaning you now have to travel to location, run the full ten minute duel for results, and that if ko'd cannot initiate a bouquet duel...

But I noticed that the energy use in doing these duels is different for duelers and every other character class. Duelers spend 12 energy per bouquet duel initiated; while soldiers, workers, and adventurers only use 5 energy.

Is this a bug that hasn't been resolved or a game mechanic that gives a shortchange to the dueler class in these?

It costs me 12 energy on my adventurer and my two soldiers.

It still costs me 12 energy regardless of my class.
