CPQ2 Ludi maze or CWK?

CWK at 51? Good luck finding a channel where people won't KS you at Windraiders. And I hope you have some escort or some reputation to teleport you up there, somehow, because unless you have over 3300 HP, you won't make it past Elder Wraiths, much less Crimson Guardians. >_>

I trained there starting at 47 and found channels quite easily. Although this could be since I almost never trained during peak times since I live in Australia.

Additionally, since he's a Wind Archer most likely he has Wind Walk which can help him get there with relative ease.
