...Anyway, moving on.

Flood maps are probably the worst maps in the game; which isn't to say that they're bad, but that they have a few balance issues. Release is just a genuinely bad map, if you ask me. I don't ever enjoy playing it. Not because the Flood annoy me, but because there's only one ay to attack your opponent with ground-based units.

Crevice, on the other hand, simply has an insane amount of Reactors. Now, I don't mind Reactor Hooks, but four? It simply gives Covenant players to much of an advantage. Combine that with the fact that there is bad pathfinding, and you've got yourself an unbalanced map that promotes using only one unit (AKA, the Leader).

Exile, on the other hand, I like. The two Reactors on each side lead to some interesting strategies and the map is a bit more strategic, in that you need to think twice about rushing and harrasment. Because if you fail, there's no time to rebuild. However, the close proximity of the two middle bases is a tad ridiculous.
