Skipping the obvious problems with 1-2, it's just a very dull point. Red gets a platform to stand on, Blu has two halls to rush down. I know you could simplify most points like that, but in this case I'm not simplifying. That's the proper description for it.
Stage 2-1 was the first time I've ever seen a defending team hiding during set-up. Not hiding for an ambush, but hiding because no one defending that point thought they had a chance in hell of living past the first 30 seconds.
The one-way door that lets out directly onto the point for the attackers at 2-2 was far too powerful, especially since you had no idea whether an enemy was about to come out or not.
Stage 2 and 3 is just too small, and like 2-1 there wasn't nearly enough cover for Red on 3-1. 3-2 we couldn't even get out of the spawn as Blue ran by to take the point.
Despite all the gripes there is a lot of potential in the map, and the lava was just awesome. The points mostly have good ideas behind the designs that just need work. Keep it up.
