The 80 point reward threshold is too easy to manipulate by bots and extractors. There are a large number of accounts that are getting exactly enough Goo points to qualify for this reward. Anyone can just walk into an arena and goo the nearest soil for 80 points.

My proposal would be to make it so that you need points in more than one category to qualify for rewards. Getting points for Guano, Spores and watering is much more challenging for bots to do and requires you to actually play the game.
