Popularity in choice =/= good mission. Each time new missions become available, they tend to be spammed as a means of coming to grips with them. Similarly, it is a mission like Highly Classified, where it forces you to mix up your troop selection in order to be viable. Ergo, it would be a pick of choice for TOs who want to force their players to be more flexible in their list building - note, mission selection is the TOs choice, not the players. Also, it was a forced selection in the Uprising mission set. You couldn't do Uprising ITS event without playing it. We played it locally, and the reason we played it was in order to play Armoury again - because Armoury is a hugely popular mission in my locale, but was removed from Official ITS for a good long while.
