I had Dark Trooper at relic 7 before the Great Nerf. He was reset to r5 and the mats for r6+7 refunded even though his kit hadn't been changed at all. The only relevant change was to SEE's kit in order to ensure that he can't (easily) be countered with Imps.
QGJ was nerfed for the same reason, to take another GL counter off the table. And in this case his actual kit and ability description saw a pretty drastic change. To flat out state "none of this omicron magic applies against GLs" is a massive nerf.
