For me both, I first played a lot of League of Legends and later started playing Overwatch.
While playing the game I notice (or can guess) what background enemies have. Some people are really skilled at shooting but can easily be out rotated and tunnel vision on fighting. I won one game as Wraith while being 1/9, but I just focused on Objectiles while everyone else was just fighting. People with MOBA experience seem to be more aware about objectives and rotations.
I second this! The game has really interesting idea and I have talked with developers and they are really awesome people.
Remasters look amazing but not worth the current price tag. I will just wait for the sale and reconsider.
