With more rewards, wouldn't it be fun?
Just like this week with the no down-state debuff on WvW, and it was a thing on the ERP (Elitist Raiding Party).
It has been proven to be so much punishing/satisfying to do raids with this particular debuff.
Also, it has been implemented in the game so it would be such a cost for the devs to put it in. (So I guess)
