People will either love it or hate it. The UI requires hand-eye cooridination and a bit of dexterity to play well.
New UI is hardly dumb or easy. Its actually a bit difficult to get used to, especially if you are fumble fingered and not used to FPS games, but it is learnable and enjoyable if you care to put effort forth to learn. Its a lot more challenging then the old method of automated combat via macros and everyone needing same skills, armor, weapons and buffs to fight each other in PVP.
In my opinion, the old SWG was much too easy. Now there's a challenge.
