I am going to assume you are not familiar with the end game and Social gear that can be moded as well as dropped gear, as that nullifies the point. you have but one set of stats so you do not need different gear in your AC even if you respec.
A macro to mount... mundane request imho.
Assist works entirely different within SWtOR and if you play with it you will find that your assist macro's are not needed. But, if you insist that you need them for such things Logitech make Gaming pads that you can set macros to outside of the game...
Actuall a ton of us do and we also realize how the dictatorship of add-ons became requirements... so much so that Blizzard was forced to integrate them to appease many. This in turn adjusted the game difficulty.
First and foremost calling people nearsighted is a bit of an insult to many people that disagree with your opinions... MMO's have succcesfully survived without the use of add-ons in the past and this one is doing fine. This is not a wow clone, and the game play, gearing system, UI and design are different and not trying to learn those differences and adapt is a myopic view of the game in it's current incarnation.
