I wouldn't mind seeing some of the more useless Ult drops being changed to cosmetic items (e.g., does Ult Green really need all those Justy drops?), but an exchange quest could be a good option for less-coveted cosmetics. I'm holding out for a Yas7k skin for Spread Needle lol.
Didn't find anything worthwhile, but I took my first FOnewm from level 70 to level 140 during the event. My first time exclusively FOing for such a period of time. I'd like to say I've finally gotten decent at nuking now after having so long to memorize enemy resistances in Ult, my higher level...
