What is the best way to level up from 50 - 60 and on wards?

[Blackcanary]

Daily duty finder roulettes, challenge logs (5 fates in 5 areas is something people miss a lot). I hear Palace of the dead is good XP but I find it a little monotonous so I didn't use it. Beast tribe quests (vath, vundu) are good and scale to your level even past 60. Hunt marks give little boosts for the daily marks. Guildhest is good for the run 3 challenge log too but is.. pretty small xp for everything else.

Sorry whats a guildhest?
