Largely lack of Steam and/or Stainless giving a damn. There's literally no prizes or anything for being high rank in this game, so why bother punishing someone whose greatest crime is occasionally dinging someone 1 point of rank that doesn't matter?
Well for me the reward for being 35-40 is that you get to play against real(ish) decks more. My abzan went 0-3 vs a pretty sweet PW deck using new Lily/Vital Force/Recursion/Mindbenders earlier, I just couldn't draw Never or Anguish in any of the games, but it was a lot of fun and my opponent played well. I also learned something after holding Arrogance in hand for 1 turn too long even though they had a Mindbender in the gy and Lili in play (mainly to not be so dumb and pay attention
). I don't tend to get good games at lower ranks, half the players seem to instantly dc and I end up playing against the **** AI using some janky white aggro deck and being bored out of my mind.
If it's only one guy, then I guess it's not a huge deal, but this is the sort of thing (alongside "network errors" and "disconnected") that can break a game. I know that if I feel that the fun matches are being overwhelmed by having to play the Ai , cheaters and disconnects then I wouldn't play the game anymore.
