Well, I spent the better part of 3 hours on Nar Shaddaa getting just one datacron, so I have you beat. And you know what? I'm glad I did it, and I went on to get every datacron on every planet. Was it always fun? Did I cuss and throw things sometimes? Perhaps.
They are not actually hidden very well since you can find directions on the internet, so without any challenge to reach them, where's the fun in that? Maybe they should randomly move locations so no one ever knows where they are?
I say strap on your boots, set your graphics a little lower, buck-up, quit QQing, and accept the challenge.
(p.s. if you didn't like Taris, you should avoid Nar Shadda and Quesh as well)
