The Crystalline Entity is suffering from a serious design flaw. Every other Fleet action I've seen people can figure out and win. With the CE, it's impossible to get a group large enough to win to work together. Everyone is so single minded in their desire to do what THEY want to do and flat out refuse to stop shooting shards. It really take away from the experience when there is such a poorly designed roadblock like this in the way.
Devs, please redesign or delete this waste of time mission.
