you would think i hate this game with how much i complain about it

Some weeks ago, a prominent Overwatch streamer, Seagull, released a video titled The State of Overwatch. This video touched upon several topics that had--and continue to be--discussed frequently by the player base over the past year, such as:

-Game balance after the introduction of Brigitte and the increasing dominance of tank/support heavy compositions;
-The ultimate "meta" essentially boiling down to "have more than the other team"
-General feeling of the matchmaker being inadequate, leading to games where teams have multiple players with identical/overlapping hero pools;
-The team nature of the game means that when your team is working well together you feel great, but if you're not you feel helpless and this contributes to toxicity and the urge to blame those around you;
-All of the above combining so that actually playing Overwatch becomes frustrating and unpleasant and ends with players leaving the game altogether

The reaction to the video has been mixed; there's widespread agreement that Overwatch isn't all that fun to play anymore, but no real consensus as to why these issues exist, or on what to do to address them. I'm no different; there are a lot of aspects of Overwatch design, balance, and approach to matchmaking/social features that have bugged me for a long time, some for years at this point, and now seems as good a time as any to voice them.

Sorry, this is going to get...whiny.

( Hero balance, why triple tank/triple support is strong, and why supports keep getting nerfed )
