FATEs and leves aren't that bad actually. They get the same type of boost that you do in dungeons. When I was leveling, almost everything that gave me exp (except any hunting logs), would give me a minimum of 170% bonus exp (with rested) until I hit 50, which then dropped to a little over 100% (with rested).
Folks should take advantage of those gather leves too, like in Costa and Coerthas. 10-14k exp for 20sec or so of running around is a winner.
