General: Overall I enjoyed the 3 maps. Although for different reasons usually.
Gameplay: Overwatch was really fun having the death pit and spike area, however the map as whole felt a little awkward for dominion gameplay. I would routinely ignore the point that took more travel distance to get to in relationship to the close proximity of “B” and the deathpit area. This goes for the same in regards to River Fort, I would ignore the elevated point. However the actual travel may be the same, the elevated point seemed to be a riskier proposition than defending the two on the low ground. Citadel Gate seemed like the most balanced map in dominion mode. Each team had a close point with a precarious side access route. Taking the odd point made more strategic sense in Citadel Gate than in the other maps. Holding a point close to their spawn means that there is the possibility to hold them away from most of the map. There was more incentive for taking all the points in Citadel Gate than in the other two.
Aesthetics: I think the aesthetics of Overwatch and Citadel Gate were excellent. River Fort’s color pallette seemed a bit muddy to me.
