After finishing the mini battle passes that DLC include, I never felt a need or a want to look at the quests again.
100 xp just isn't worth it at all.
I know that you are guys playing with tokens and palprize right now, but making DLC give +1 token after completing them would give an incentive to comeback to these fellas.
And If a token is too much to ask for, at least make it +750 xp (same way the daily ones work).
