FunkyProblem is we don't really have maps to replace it, I mean we have metalworks and sunshine but nobody likes those maps. and most new maps we're getting atm don't really look promising at all.
Edit: I don't actually dislike reckoner really. I just feel its pretty similar to process/sunshine so I would rather play Granary over Sunshine or Reckoner. I feel sunshine is a more complete map but I don't mind playing reckoner either. I mostly just miss Granary.
