Why Team Fortress 2 And Overwatch Are Not As Alike As They Appear

Let me give some quick background: I used to be hard into Team Fortress 2. It was my most played game of all time, and probably still is, at around 2500 hours. I loved the game, but over time became disillusioned with the path the current design team was taking it in and fell off the bandwagon. At the time of writing, I have not touched the game in over two years.
