That's why i guess Nutaku still giving pero burguers despite EG event ended, to prevent stacking of items. I don't see this bad ("game balance") the bad thing is the gap made against low/mid cashers. As i said before, daily deals was cut since some time ago.

In the past, you can find 12 mid pudding at $3 (as daily deal, once per day), made for this kind of events. Now this was cut and packs costs more, keeping only the packs for whales.

Other good idea was the half pack (1 half pudding + 1 half peronamin), made for perogambit and was pretty cheap (with the same limit, once per day).

Nutaku can clean a bit the stacking disease with those measures, but if they forget again to fill the gap made, more casuals will drop the game.
