This has very little to do with the 'loading screen' stuff if you ask me.That was hardly meant as an insult. You need to open your eyes. The argument really boils down to you think it's a balancing factor because some people are not patient enough to stare at loading screens. I think that's absolutely ridiculous and a poor excuse for balancing factors. That's like saying in Call of Duty... Well tell you what. You can have a minigun, BUT, you must only spawn with 1 minute left because it should take longer for you to reach the battlefield cause you have a minigun. Or just properly balance it and make it have a spool up time and be innacurate. Much like you can properly balance the ships to fit the roles they were designed for. There is no jump a long way role.
Space in Elite is enormous in terms of scale, it takes time to get from a to b, some ships are better at it and gets there faster, this isn't about making people wait, I can't imagine they have done it simply to make people wait, in my eyes they have done it because, well, space is big, and a combat ship in their eyes is not meant to get from a to b as easily as other ships.
Also your example is flawed, a lot of games punish heavy weapons with slower movement, often significantly so, so it would seem to support the same view as frontier has.
