As of the late evening on December 19, my limited map pool changed to:
… --> Cursed Hollow --> Dragon Shire --> Tomb of the Spider Queen --> Alterac Pass --> … Cursed Hollow --> …
with all the prior described behavior.
Low priority though the issue understandably might be, it has been active for far more time than it has not since August. I am a coder and cannot for the life of me figure out what could possibly be so difficult about fixing this problem permanently in a time span of four months when the solution has actually been realized—accidentally or else wise—in between the returns to broken behavior. After the first two months or so I presumed to speculate as to what the culprit might be, but received nothing whatsoever for a response.
The current in-game event is now more than a quarter over and we’re looking at the likelihood of yet another full week of four-battleground purgatory, with no indication other than a two-week-old response, which thus far has transitioned to no substantive results, that the issue will be resolved before the event has fully concluded.
This is getting very, very discouraging.
