The X Wing was designed for a completely different game, that just happened to share the same name and dev team. The problem isn't the jousting efficiency, its the lack of reposition or autothrusters, since those things obviously weren't concerns back then.
Well. Both the TIE Fighter and TIE Advanced were released in Wave 1. They both have some great repositioning ability.
And it was actually a different team. The current developers first worked (jointly with the originals, iirc) on Imperial Aces.
