Ranked 5s up for a limited amount of time per day ?!?!

I don't think ranked 5s should be up in a certain period of time each day cuz everyone has their own free time that they can spent with their freinds ! Not everyone can get 4 friends to play from _ TO _ hour. Queue time isn't gonna be a big problem for people who have the time to play and for those who don't - they are just not gonna play at that hour.Last year me and my friends played a shit load of ranked at a time when almost nobody played.We waited how much we had to cuz that was our only free time at the day that we could play together.And on top of that dynamic queue has pretty big queue time too so it isn't gonna make a difference if we wait a bit more than usual to play some ranked with friedns who aren't at our elo and cant dynamic queue cuz of the restriction or simply they are just at lower skill cap. At the end of the day thats just my point so people may have a different opinion.
