I think it's just right. I did lot of space combats as it was fun and quickly outleveled Taris... I ocmpleted my class quests and moved on to Nar Shaddaa.
It did suck a little that I couldn't complete Taris as I "have" to complete something in order to move on but in the end when it comes down to it I do prefer having "more".
I can always come back at level 50 to see it but more importantly my smuggler alt will have a whole new planet to explore and leveling him will be that much more fun.
