51+ Where are the best quest?

[bugilt]

I finished most of the easy for multi boxer quest in Felwood and also started the EPL quest. What is the best route from this point on? I would like to find more quest, but I wouldn't mind some instancing if it's multiboxer friendly.

Un'Goro, Felwood, WPL, EPL, maybe BRD/LBRS.

Yup.

Searing Gorge
Ungoro
Azshara
Felwood

[Eteocles]

Ehhh I was gonna say Searing Gorge too but the highest lvls there are 49 mostly; not worth it post-50, just around 46-49; Azshara's good as I know the Hunter and Rogue lv50 quests take you through there anyways multiple times so it should be a 50+ area

I'm going to put my money on plaguelands. Lots of kill quests if i remember correctly.
