As mentioned above i cannot believe people cannot see the following:
The troopers mortar volley takes longer than the BH's mirror. (by two secs)
The warzone with the cannons have two of them already facing the Republic ship causing the Imperials to get points quicker even if the Republic opens with a 2-cap.
I don't think Intel HD Graphics is a card. Its probably integrated graphics. Your rig is definitely enough to play SWTOR nicely if you had a standalone GPU to support it.
You can get a GTX 550ti (1GB) for $135. That card along with your existing specifications should make your gameplay alot more playable.
I loved WoW, it was a terrific game. But i am done with it.
I have to ask you a question though, how are you coming to terms with the new talent trees they are releasing in the panda expac? Seems really really lame.
