I think they should remove shapeshifting cards from the group wheel and place back mood scrolls, not dangos (that way would make sense to get them in event or to actually waste 1200 arena currency to get them for the weekly in monthly event).
Dangos have to stay in the wheel but i could agree on the fact that the chance to get them should be lowered a bit in favor of level 1/2 magatamas and chakra packs there (the chance to get coupons is not low at all in that wheel so the things are good as they are now).
