More auctions.

Seriously though, each time there's an announced "auction weekend" on Era he makes like $5k in gralat packs. And this is from last year, with a lower player count. Moral of the story, less hats/more pointless weapons etc=more money  

Need less auctions of the same thing though to keep items slightly rare...  

True, plus variety lets you milk more cash from the same crowd  

And there needs to be auction items that aren't meant to be rare that can be auctioned quite often.
