It’s been 2 days when I can’t do Higher tier NM Sigils tier 100 and Glasure 96 and the Pit tier 70-73+ mobs and bosses. The Hp doesn’t go down as was used to for my level, usually goes down fast and smooth for my level 100 heart seeker rouge build… GM Adruduzect, told me to report it here but he accidently put on wow forum. pls I need help do i get neithron compensation for this bug? Open world mobs and bosses like hell tide , legion, and such’s is fine just the dungeons like tormented Duriel, andariel , Gregoire the pit mobs and bosses… TYVM for the Help in advanced…
