Me and my buddy at lvl 44 out in the wastelands of Hoth looking for that silly probe... dodging a full group of lvl 50 sith also looking for the probe XD. Or my 2nd balloon flight where we had an sith inquisitor that wanted to do it too, rode the entire balloon until it bugged out just chatting with her.

How exactly do you do that? Would be great to use on an alt, but I'm drawing a blank.

Well sure if you want to misquote me. Anyway, I did the datacron with a friend I've known for 25 years so the whole doing it with other people still applies here (though, I didn't like my guild at the time in WoW)... that said, Ragnaros was undefeatable when we attempted him, and on patch day, we were the first guild on our server to down him. So the feeling was very similar

The Tatooine one took me several tries... not because I missed the jump, but because the balloon would bug out about 30 meters from the sandcrawler and drop me on the dune below. But the feeling of relief/satisfaction when I finally got it on the fourth attempt was fantastic, like finally downing Ragnaros (not new Rag, old Rag back when all the cool kids ran molten core). None of the other datacrons have seemed hard really. Turn off sprint, line stuff up and do the jumps with WASD + keyboard (more reliable than mouse).

Flashpoints are easy once you develop a passionate fear of geometry. Remember, friends, geometry is bad and you do not want to be near it.
