Yeah, I got sky at 71, and although the perm rushed straight to sky to try and exp there, unless you know what you're doing and where to camp, you wont get anything decent at any level. We ended up doing Ro'Maeve for the remainder of time. (I think I must have collected 50+ Stacks of Wind Crystals total from 70-75 on these guys.

)
Only time you'll see yourself exping in sky really, is in a 75 Merit Point party (these guys generally know what they are doing, I was in one and we were hitting Chain #6) Or if absolutely everywhere else is full, which will only happen at this level if you exp at JP times at a weekend (Which is like 2PM for me, so I do this a lot).
I sort of shake my head when I hear friends trying to do ZMs at like level 60-65 (And complaining ZM8 is kicking their ass, no less...) because the zone is really kinda useless unless you intend to do gods and stuff, and chances of doing that before your whole LS are 75 are slim.
I got a bunch of my 70 friends to sky the other day. Took them on the tour explaining how to avoid getting yourself killed, how to get around, how to avoid accidentally fighting Ark Angels, and how to Wide Scan to make sure you don't get jumped by this "Despot" thing that likes to kill me because I have no idea if he's up or not :P.
After finishing and taking them back to Hall of the Gods, the RDMs response: "Boooo, sky is boring." And yeah, unless you got a reason to be there, it is.
