I played a game called “war of legends” a while ago. I remembered it had a feature which gave chests based on how many hours you played in 24 hours. There were about 5 chest the first was a very basic chest and the last one was the best It took about 4 to 5 hours to get the last one. If daily quest is not possible then at least this one. I think that game had both the features anyways it was about 5 years ago I don’t remember it clearly. This will turn beneficial for flare games as well (more time playing).
I would love this. Like for example daily achievements to do 10 complete raids by matchmaker or earn 100 trophies or such stuff to make the game not boring outside war
