A21 is a "carrot" dangling in front of base takers noses. It was created with uncapturable GV bases in proximity for a "coordinated" attack.
I understand the complaints, and feelings that there is a better GV battle to be had. But I am not buying this is a mistake, rather it is a rallying point. No fights anywhere else (which btw hardly, if ever, happens on this map) then THERE is the ever present challenge.
Thanks HiTech, for fixing the CV port issue while juggling alpha coading as well.
