Guild Wars 2

Neat way to be out of range against opposition, but is it technically allowed?

I would say yes unfortunately. But likewise there are professions that can hit them due to bugged AoE.

looks like the garrison.

you should go and use the ramp that lets you jump up to the top of there.

its high enough to be out of range of the keep lord area so you can’t aoe from the top down, but its close enough to the sides to be able to hit people coming in from the gates. try it out
