People tend to misinterprete what tractor beam is meant for. The beam doesnt pull something more because it is less massive, it pulls all ships the same speed- that being said, the tractor beam actually works best for brawling enemy dreadnoughts, pulling artillery cruisers out of position, and pulling tacs out of cover (against slow ships, not small ones). Dreads do not have any anti-corvette support because they are not supposed to trump corvettes or be taken out by corvettes, they are pretty much neutral- this kind of rock-paper-scissors gameplay is what supports teamwork. You want to play dread, but you dont like corvettes? You better have a destroyer by your side. Thats the way the game was intended to be played.
Hope this helps
