Well, we are all aware of the lacking ability of the ISD but it was done that way for an issue of balance. The only options with that ship were to under power it so that the game is balanced and no one side can completely over power the other, or we make the ISD a single ship only fleet. We tried making the ISD 23CP to equal out its power, but no one wanted to use it because of the inherent weakness of the ship. Even in the movies, an ISD falls to heavy Frigates. It cant maneuver with them, and its weaponry is too slow. To increase the power anymore then it already has gives the imperials a ship thats nearly impossible to kill. And whether or not this was the case in the movies, when it comes to a game not everything from reality can transfer over correctly. To give the ISD anymore power imbalances the game.
Also, the problem is not so much that the ISD is under powered, your just facing off against someone who knows exactly how to kill one. I have studied these ships enough to know where ALL of their weaknesses lie, and just like in a pokemon game, I will exploit that weakness in every battle. Its just good strategy.
Now, back to the tractor beam issue, while Eids idea may work, it still leaves with a "this and this is this unless this or this" situation. Over complexity, to which we have all agreed is bad. With his situation, we not only have to keep track of where everyones shields are at, but the amount of movement they are making, as well as re-figure everythings UCR, to which every ships will be different. On top of it, your adding ranges to it that must be kept track of as well. Many issues that could cause confusion and create unnecessary mistakes.
Also, it makes no sense that a ships speed would be effected by not its maneuver? And besides, like I said, tractor beams never stopped a ship from being able to move, only fleeing to hyperspace. Take empire at war for example. In a tractor lock ships can still move around, they just eat additional damage from the ISD. My idea does exactly that, without adding any of the complexity that Eids idea figures in. Im not saying Eids idea isnt good, im just saying its too complex for the spirit of our game.
