As someone that's been watching games exclusively on TV for the last 20 years or so, it's not that bad and you certainly get used to it. What you do miss is seeing what's happening where the ball isn't. How the team and moving, who is gut running, how the transition works. The very few times I've watching a live match the focus was always what was happening away from the ball.
The other downside is when you offer a competing point in some debate, there's always some feral who will come out and tell you that you have no idea because you weren't there.
