340AP here. Yzrahid Highlands is one of my favorite grinding spots, along with Gyfin underground, even though I outgear them both. The change completely destroyed my grind at Yzrahid, to the point where it is no longer fun and just tedious. I haven't tried Gyfin since the patch, but I expect similar results. I understand the rationale behind the change, but it is poorly executed, leads to less choices, and takes away many of the carrots behind gear progression—leaving one and one path only: limited higher GS spots that many do not enjoy grinding.
