I think that having similar vote rewards as seen in Agrarian Skies 1 would work just fine. Kamas, buckets, and reward bags. Heck, just having plain old reward bags as the only reward available would work fine.
I like the idea of having them similar to Ag. Skies 1's vote rewards. I thought it was balanced for rewards.
Lucky blocks aren't in AG2 (I don't think) so it won't work My vote is that we have them as reward bags, instead of having them the same as AG1 (Just makes it a little more unique and surprising)
