Misfiring isn't the only problem with alien. Paint pealing, bad connection with tanks/resistance jumping, TC problems, connection problems... Also it died on many people.
As I said, on paper it looks great as did Cuboid. But I really don't want another mod that will make problems only after one month.
I've never experienced these issues. They did recently release a newer version, maybe it was to address these issues you're referring to. The cuboid was rife with problems, and still is...they outnumber the issues with the Alien by a large margin.
