The quest log (timer) would write "You need to wait until tomorrow before repeating [...]". Limited : current day+1 (no hours)
- + No need to log on at the same hours to get your rewards! (More possibilities to manage your times like you want!)
- - You can take daily queen reward at 23h59 and at 00h01, making you log in only once every two day! (Kinda defeat the purpose of it, I know)
Alternative :
Once per day with a minimum of 4h cool down. (2 timer quests/sub-quest, both must satisfied to repeat)
