i just did the northwest guiding light puzzle in sorrow. i did it successfully on my own, not grouped, but i didn't get credit for the achievement. i have it for all the others. is it bugged?
I've also seen people have issues with the achievements and buffs from all districts puzzles, even after actually engaging.
Meanwhile, if it doesn't bug, you get the achievement and buff without even touching a switch, as long as someone in your group does and you're close.
This text used to say "Main: Dragonknight Tank". Way before subclassing, my raid leaders made sure I had many identity crises on both roles and classes. I tonked. Or dodoed. Or healed. Updating accordingly.
Main: Stuff-doer on a wizardry game. Still enjoying it. DK tank? Retired.
