Camps like paineel guards

[Swish]

Specs will be good til 49 at best, you're probably seeing 1/3 or 2/3 as light blue already.

Nobles used to be good til 54 but I think these days the vendors aggro if you pull them so that sucks. Have you considered Grobb guards? They'd probably be good til just after 50.

Paineel guards do have a few gaps but you can start at the two at the base of the lift around 18ish from memory (though the super green ones you've been killing upstairs in that open courtyard might be the same level), then work around to the grassy outside area with the 2 guarding a portcullis doorway then continue on around to the bank ones. There's definitely gaps along the way! Maybe look at a trip to Highkeep after bank area guards and before doing the higher ones in the courtyard on the level where Latorl walks around.
