Feeling the same. Maybe it's better with an organized team VS an organized team, but just random brawls are pretty trash. I played 8 and got a draw on 3 of them. It seems a given that there will be a combo of at least two Bastion/Torb/Sym guarding the flag and derping while doing nothing if the enemy isn't pushing. The only caps I've seen are team kills and the enemy pushing in just enough to draw defenders off before a Winston jumps in to ninja the flag away. Had a pretty sweet game where I got a teleporter in an alcove near the enemy's flag and a Winston got wise to it. He'd cap, jump back to spawn, port in, cap, repeat. Dunno if the enemy team ever figured it out.
The shear number of Tracer/Genji/Sombra who think they're going to go in solo to cap is annoying as hell.
Feels like Blizz was right and Overwatch just doesn't lend itself well to the game type. At least they put effort into it and expanded the levels and made the run back from death pretty lengthy.
