Flight should not be tested on Koltyr - that would lead to an air traffic jam.
why not? have a big stresstest to check how performance goes, doesn't matter on which map, it just needs to happen
when they did OMFG, we had like 3-4 platoons of each faction in just one biolab, and it was crazy as hell
Koltyr has one of each major facility, and two sub-bases to every one of them, so big enough for big fights
that's the reason why many players want the Battle Islands, the maps are smaller and the fights are more packed
