As soon as the new expansion Sentinels Fate launched, people were gaining levels like crazy. This is mostly due to a broken Ring even in the zone "The Hole". with a good group of 80's you can start this ring event and kill the mobs as they nearly instantly respawn, over and over. Do not spawn the final boss as he is a raid mob who does some serious damage. Just keep killing the heroics and start gaining levels. Be sure to have a couple power regen classes in the group, and good DPS. People were doing this and reached lvl 90 in about 5 hours.

This was patched and no longer works..

yeah, people did reach lvl 90 in as low as 3-4 hours with this, however it was fixed about 5-6 days ago.
It sucks cause it was fixed before i discovered the bug :-\ ah well
