My most urgent would be, for the safety of some players:
1) Flashing Lights Warnings: Epilepsy is a very dangerous ilness, and the flashing lights can cause a horrible health problems, even death. Its even more dangerous when you are alone at home, and you get this flashing lights bombarding. So I'm not asking on my behalf, just for the safety of some players. (if I may I put an link about this illness: https://www.epilepsy.org.uk/info/photosensitive-epilepsy)
2) Give us an option to switch off the shiny effects on the armors etc.
Have you seen a permafrost dyed griffon skin: Fire pinion? I did and I had to go to the place where my eyes won't get insane.
Same with a lot of skills, they are just too shiny, too much effects, too much flashing lights. It HAS to stop, really.
And there is a lot of feedbacks like mine. Way too shiny, it's just not necessary, people will be also happier when they will get some beautiful, non-shiny armor sets or weapons. We will survive this! And my eyes at this point CAN'T survive this. Legendaries should only have some extra shiny, but Ad Infinitum is that shiny that I can't see my character.
