I for one would like to think that Game Grumps wouldn't have turned into this hollow, soulless, out of touch machine that just superficially resembles what it once was had Jon stayed. He probably would not have allowed the show to become what it is now, he would have kept contact with both positive and negative fan feedback, not just the dick suckers, and most importantly he would have stopped Arin's head from going so far up his own ass. Arin obviously just surrounds himself with sycophants who can never muster up to give him criticism of any kind (not that he would listen anyway, because he's a thin-skinned prima donna), while Dan is just a spineless yes man instead of a co-host of equal standing, and Jon was definitely not these things. There's a reason why everyone considers his episodes to be the golden era of Grumps.
