There are a ton of good reasons for removing 5 queues in immortal+, most of them valid and backed by evidence. However, nothing beat the grinding with your friends to make it to the top. The gradual improvement, the fluctuation of ranks. Eventually, we get to immortal and now we have to split up into duo queues, something that sort of pushes the group from talking in discord. I wish there were a way to 5 stack without ruining it for other players
