Beer festival yields loots way faster than I can spend them. Is there any use for hundreds of them? War outpost is finished (if nothing changes, the universe as we know it will not see those 1e300 stepping stones), Midaeum is finished, everything that can be bought is bought. I got about 1/1000 of the amount of diamonds I'd need for the next champion, and there's hardly any progress. If it wasn't for pets and beer, there'd be no reason to come back within the next couple of decades ...
I never thought that an idle game might be that addictive ... but just my two cents: It has been said that some kind of statistices would be nice - I can't agree enough. Another thing that would be nice to have is some kind of upgrade to the managers (maybe "manager" -> "CEO"). A CEO should be able to autonomously buy additional units/upgrades whenever there's sufficient money. If I can tell him "Stop at 900" that would be a bonus.
