Yep, Tractors and transporters seem to have less value than other subsystems. Personally, like many others, I prefer to spend the ship mass on more important things such as computers, armor, and cloak (for kling/rom). Plus, regarding tractors, we've all seen repeated debates surrounding the topic of the tractor pull technique. In my experience, I've rarely seen anyone in an equal or lesser ship class than my own who tried to attempt this maneuver against me. In every case, I've been subjected to this tactic by a larger, more powerful ship. Therefore, what good is spending money on a good tractor when your ship's mass restrictions still wont allow you to repel a full powered tractor from a greater ship. From an offensive standpoint, I only employ the tractor-pull maneuver with exstremely lesser classed ships who are more of a nuissance than a challenge, therefore eliminating the need once again to waste mass on the best available tractor for my ship.
However regarding transporters, I read in one of the other threads that you get PP bonus for using marines to do H & R's . Has anyone confirmed this as a fact? Depending on the value, that could make me adjust my strategy somewhat.
