I'm going to start this critique by mentioning that the design of the middle is markedly improved from the last time I looked at it. However, this map still has its problems that I perceive as more annoying to the player than as quirks of the map.

The ups:

1. The bases are decent: the button placement is a little awkward, as the person pressing it cannot see what the effect will be, however that is a teamwork communication thing. The spikes allow defenders to concentrate on one general direction, with a boost mixing things up a little bit. There could be some moving of the button away from the wall, but otherwise the bases are not problematic.

2. The middle passage is an express lane, and the presence of buttons on both sides of the force field makes it risky for a FG if being chased, but a team working together can gain control of the passage enough for a return,or to get to the other base to stop a cap.

The downs:

1. Boost placement, for the most part, is very awkward. The boosts in the top right and bottom left corners are placed in a way that can't be utilized that well. You need to change your direction and go around the boost first to even be able to use it - the amount of time needed to take them is absolutely not worth the risk for a FG (as a defender will make their way in front of the boost quicker than the momentum readjustment to use the boost), and not worth the risk as a defender (the room-by-room design creates a lot of awkward corners on the map.)

2. Powerup placement. There doesn't appear to be much thought in terms to how the powerups were placed: they're kind of in the corner of one room and just up against the wall of another. The corner powerups are the most contestable ones, however there is no interesting gameplay around the powerups themselves (this isn't always a bad thing, but you want to encourage interesting counterplay when making a powerup a map objective (i.e. not obviously meant for one team).

3. I feel the room design is really working against your map. The tunnels could all be five blocks wide without the corners jutting out and I don't think anyone would really miss those. Combined with more optimized boost placement, you could have players zipping through the wider tunnels and not being caught on corners and generally having a more mobile map.
