Honestly, my experience of most SWTOR levels (including Coruscant) is:- navigate through map to class quest marker and/or main zone marker, exploring all the nooks and crannies on the way. In doing this, you pick up local quests that usually involve killing the very mobs you’re having to plow your way through to get to the main quests, plus there are bonus quests that are revealed as you are killing the mobs. By the time you get to the class/zone quest markers, you’ve finished most of the little side quests and bonus quests, you then retrace your steps and hand the quests back in reverse order till you get back to the start of the zone (or there’s some other cutsceney way of getting out, or you can fast travel out).
IOW, you’re running around a lot of the time, yes, but you’re usually running through groups of mobs that you have to kill to fulfil class/main/local quests, so you’re very seldom running around to no purpose. Nor are you ever at a loss as to what you should be doing next.
I agree that there are large areas with nothing to do like the Senate, that you sometimes have to run through to turn in the mq or whatever - but I don’t find that happening so very often, or being so irksome (since the zones are usually beautiful and immersive to stroll around in anyway, and there’s always fast travel).
Another way of saying this: in WoW and many other MMOs, the quest structure is something like “blob of radial quests - move - blob of radial quests - move” etc. Whereas in SWTOR it’s more linear, it’s like “aim for MQ, hoover up and and do quests as you go, do the MQ at the end, finish”.
Or, again, you could say that the same “quest blob - move - quest blob” structure is in SWTOR, but it’s scaled up to the level of the planets being the “blobs”, and the “blobs” themselves aren’t blobs but little linear paths, or at most “quest fans”, and the “moving” betwen them is done by spaceship.
