eeeSpe0Make it a good spectator sport. Let's not kid ourselves here, comp tf2 is not as fun to watch as something like cs, smite or even hearthstone.
Good is a bad word. Easy is much better. TF2 is fucking hard to watch for me, and I can actually play TF2 at a level 99.99% of the tf2 population can't (pls no shittalk). Until the game can be broadcast in a way that's more clear and concise, it'll always be hard to watch. CS and MOBAs have the leg up here because they're primarily 2 dimensional and very focused/predictable. Combine this with how easy it is to program the predictive camera for CS compared to TF2, and you end up with much easier to spectate games. Simple round structures, relatively few objectives, very clear cut measurements for success. CS has these and as a result is very simple to spectate. TF2 isn't impossible to cast, but it requires a very good group of people to do so, and even then its more of a players' cast than a viewers' one. The people who're actually watching and understanding probably play TF2.
TF2 is obviously always going to be more difficult to watch than other games, but I feel like the casters and cameraman sometimes make it a bit harder. People constantly say the cameraman and casters don't always understand what's going on and they usually follow the wrong action, but it really is true. Rarely do I hear casters talk about what they think will happen/should happen based on ubers/numbers, keeping it super simple. There still are a few casters who do a pretty good job of this, like Avast, however. It's just kind of upsetting to watch casts where someone dies and the casters are so confused why the other team pushed.
