Canalzone was interesting but ultimately just not enjoyable to play. I honestly liked the idea of it and maneuvering the map was fun, but as soldier all I really did was cap points. I also played a handful of lobbies as heavy on canalzone and all I did was defend the same two or three points. I'd consider those to be the two extremes: the roamers who cap and the heavier classes + medics who just defend the points that give them the most advantage. It was just a boring map to play on. Easily my least favorite map of the season.
Standin, on the contrary, was fantastic. Both teams hopping back and forth between three points made it really fast paced and dynamic without being, well, canalzone.
Obscure also gets a mention. Best 5cp map of the season. I really want to see it come back. It feels like granary except with a midpoint that's a little more suited to highlander.
