Losing customers due to unhealthy community due to too large of arena doesn't get fixed by re-opening the game to the large numbers that originally cause the unhealthy community.
Quite the opposite for the offpeak arena bringing together the entire community to work together to either 1) take a base 2)defend a base 3)or up a fighter sweep. For once in a very long long time, this 1 arena concept allowed the rooks to get their 'organization' factor back to join any mission and be successful.
Something that had been sorely absent in the 'old method' of two late war arenas.
It reduced frustration, it focused the effort. It's nothing short of a miracle.
Now... If HTC can only fix the peak hour max cap that splits apart my squad and other's who prefer not to fly (like myself) until cap numbers come up to rejoin their squadmates.
