I like this game so far - not going anywhere soon, but it has huge problems, thats for sure. My 2 main issiues would be:
1. Ability dealy. As a pvp guy this is killing the game for me. How this passed beta testing is beyond my mind. After 6 years of pvp in WoW i was really used to abilities working after pressing a key. If this wont get fixed ill move on to greener pastures.
2. Terrible optimization. Maybe my rig isnt top of the line (im getting a new one soon, that doesnt change anything tho), but its well above minimum sys recs. While leveling everything works smooth like butter, but when i enter a wz hell breaks loose. Hutball is "playable" (slow but still), other wz (like that one with 3 turrets in middle, dunno how its called) is basicly a slideshow. And lets be honest, graphics of swtor range anywhere between medicore and flat out terrible (armor textures anyone?). Other new games, with graphics way ahead of swtor, like Skyrim, BF3, Deus Ex are working perfecly fine on high settings (except BF). Not to mention WoW, with everything maxed, except shadows, i can play 40v40 AV without any problems, while here my comp craps itself with 8 enemies on the screen.
There is a lot more wrong with this game like lack of addons, macros, no endgame, no dungeon finder and so on. But those 2 are imo the ones that drive away many new players.
