These are the reasons I have discontinued my subscription -
I always had the feeling that I was merely a clone of all the other gunslingers out there. The armor is pretty much 3 or 4 appearances, with a few color details, but for the most part, we all look alike, depending on what we're doing (PVE or PVP,) We can't be individuals in our clothing styles, since it appears that we're supposed to wear the same exact thing day after day. I will also admit to simply hating the "gunslinger" motif - it was cool when there weren't so many running around. And now that we all have the cute pet, we're looking more and more alike than ever.
So there's that. And then there's the ships - as a smuggler, I have pretty much the ugliest ship in the game. At least, I'd have liked to decide if I was such a slob or if I was actually capable of improving things onboard. We have no ability to make our ship unique, either through skins or with actually furnishings.
With all the cut-away scenes and loading screens, I was never really able to feel immersed in the environment. Game play, as a result, never really grabbed me.
Anyway, I just feel sad that what I'd thought was a wonderful way to portray the Star Wars saga, ended up looking and feeling more like a solo-player PC game.
