To be honest, all of this is just reinforcing my doubt of how well the TF Team understands the game and the content they're releasing.
They completely ditched Gravel Pit-style A/D as a gamemode "because it split up teams", even though Gravel Pit plays better than most of the Attack and Defend maps in the game.
Asteroid has archaic 2fort-style design.
Then there's the weapons and the completely unnecessary Heavy nerf from Love and War...
And now this. They cut a map from an update that desperately needed something extra, a map that's fairly straightforward... for being too complicated and difficult.
WHY?
Maps like Steel and Standin (Asteroid, even) weren't cut for being complicated or difficult for new players! Snowplow is practically Attack and Defend with a glorified timer, for Christ's sake! This seems like a bit of a double standard on the behalf of Valve, and it's making me question their judgement more than ever.
Regardless, best of luck to the two of you in the future. Snowplow's gathered a bit of a following, and I think it's come to be something quite nice in the end. Hopefully it will pave the way for custom maps in the future, even if it got left behind.
