Best way to level your level 50 alts to 51

[Zfz]

Efficient way is 50-55 in N Than.
Once you hit 55, spam the Aery.

What do you do with your gear though? Assuming you don't already have full sets of 130+ waiting, The Aery is a Lv 55 dungeon and you're supposed to be wearing at least 133 HQ quest gear. So at least 130 Poetics gear.

Instead you would go in full 120 Poetic?
