The Shroom Drive, is ridiculous on all points...
So the saucer rotates in two different directions after engaging the drive, before spinning the entire ship on it's axis. These writers and directors know there's a little thing called INERTIAL DAMPENERS right? Cause without them, people would be a bug on the rear wall whenever the ship went to warp. Add to that, having the entire ship spin in various directions, would seriously compromise the inertial dampeners, and put a huge strain on the ships energy.
As for the "Lorca maneuver", that entire rescue (like Tally mentioned), was pretty stupid considering the alleged importance of this colony. No backup ships nearby (as always, the "hero" ship is the one closest to where they need to be), and even after destroying all the Klingon ships, Lorca just casually spore warps out again, leaving the colonists to wonder... Hmm, what happened? Also, what was the point of the 2nd spore warp, when there weren't any ships left? Wouldn't conventional warp have sufficed? Or could it be that the spore warp technology is so secretive, that they don't even want the rest of the Federation to know about? I.e Section 31 operatives... (I know you've mentioned elsewhere Tuskin, that you don't subscribe to the Section 31 theory)
