True for first three.
4. Muttrah crashed as well after but it is true that initial assault was a disaster for 1-2 squads due to enemy's armor and CAS presence in Docks. Hater sq though had established one FOB north from the Docks and there was some progress untill the crash happened. Not sure if intended but it was quite a challenge to tell apart friendly from foes (almost the same camo and weapons).
5-6. Both Khami and Barracuda were played with roughly 20 players at best so event was almost done by then, probably because of both crashes (mostly Muttrah one).
-Khami was almost a success but we failed to secure last 1-2 flags and we lost to the bots.
-While at Khami lack of manpower was problematic, at Barra it pretty much finished the event. Even with full 4 SQs and CAS support it wouldn't be a walk through the park. With 16 players who were still playing it proved to be impossible.
Neverless, event was fun while it lasted. It seems like ticket problem was successfully solved and only major issue were those server crashes.
