When my roommate did the RAF leveling...

He granted 30 odd levels from one toon to another, and then logged a second toon on for another 30 odd levels of granting.
The toon in question was leveled to 2nd, almost 3rd level and then granted to 60th.

He had someone send him a tell, asking how this was done, because the guy wanted to level the same way.

My roommate responded with: It's the current event, there are ultra rare herbs around called Feycrack. Clicking these, will have your toon level up. They're very rare, but I've been farming them all week. The guy was extremely interested and wanted to know where they were found, and if my roommate had any extra's which he'd be willing to sell etc.

It was extremely funny to watch.
