What about all the times (in WoW) you'll be at a mine or something and the commander mob is shouting at the mining mobs to "Hurry it up! We've gotto get the shipment ready in time for blah blah..."..
That is an effort at making the mobs more immersive that SWTOR doesn't have anywhere. There are no patrolling mobs in SWTOR like there are in WoW. And the fight outside hutta is half-assed - if you kill the mobs they're shooting at the NPCs just keep shooting at thin air. That's not how it works in WoW at all, the technology there is alot better and more immersive, even though its much older.
There's ambient sounds everywhere in WoW, birds chirping, waterfalls, etc. None of that in SWTOR. And you didn't even mention the part about the wildlife (because SWTOR barely has any and the few it does have are completely stationary). Not to mention swimming, sitting in chairs, all these little details that on their own mean nothing but taken together make WoW much more immersive than SWTOR. There's barely even any music in SWTOR (compared to WoW where it plays nonstop)...
Take a look at these videos, take a look at how static and dead everything is:
NPCs stand frozen in unnatural poses:

This one especially says it all:

Where do you see this sort of thing in WoW, and why do you excuse it in a modern MMO? You're telling me the devs couldn't take 2 minutes to create unique NPCs? Even the guards in WoW have unique faces.
I just did.
And lastly, how come its always daytime? And why do all the planets look EXACTLY LIKE EARTH??? It's either a desert, an oak forest, or snow. This is supposed to be space, where are the alien trees? Where are the electric clouds? the Burning Crusade has more imaginative alien-like features than SWTOR and that was 5 years ago!
