Well, I've tried all the new servers, and my opinion:
NYC HA:
Beautifully executed. Although it's the almost same exact thing as the Virginia HA, I've always loved classic Hero Assault.
Force FFA:
Not so sure. At first, I wasn't really sure if it was FFA. KingLol and I were wondering about the genuinity/genuiness/whatever it is. Anyway, I don't really like it that much, I don't know if it's that the tk doesn't feel right to me, or what. Anyway, you probably won't see me on it much.
The Dallas HA: I don't even think it's up, I'll check again.
