I said this before, but I believe that we are seeing in theses arenas, what we will see in CT.
Think about it ... CT would never work with the puny amounts of ack that we were dealing with prior to this change. It just wouldn't fit in the type of scenario that they are trying to simulate.
HT is using these arenas as a testing ground, and at the same time, converting these arenas to be training grounds for those who want to fly successfully in CT along with making gameplay in these arenas more challenging and fun.
Can't wait to see more changes.
