This is in no way a demand or a must have, just a suggestion I find cool.
Now sometimes when im playing, I chat with friends or cast spells. So, you know the brightness dims down when you cast spells right? Or sometimes the brightness of the game stays low after chatting with your friend from the menu while in-game or just doing some settings (not sure is it a bug or what but Im not complaining).
And tbh, it looks really nice, like night time or a change of atmosphere for Duelyst. Like I said, it’s jsut a suggestion and a thought I find intriguing, not a necessity. Maybe have this happen during night time in Duelyst from evening on wards to give a change of atmosphere maybe.
