@Riot Regarding Dynamic Queue

You don't have to make a second ranked mode. You don't have to split the community. The fix is easy...

• Remove 4 man queues. This has been obvious from the start. Everyone complained about this BEFORE and after release of dynamic queue. DotA 2 has had "dynamic queue" in their game and has almost always restricted it to teams of 1, 2, 3, or 5.
• Make it so if you queue solo, you only get matched up with solo. This way solo players get the true solo experience and can climb the way THEY want to. The ranked system is still EXACTLY the same and ranks, pre-masters, aren't determined by how good you are relative to others, it's how much you win, period. /***/
• You could also make it so if you queue solo, you only get matched up with solos or duos. Duos can still be matched with trios, though.

// Yes, this will split queue times at higher ELO. Restrict Higher ELOs to max of trios, no 5-mans. This will also not fix the "problem" of people climbing easily (why is this an issue anyways?) but it fixes the people who'd rather solo climb. There's websites, like OP.GG, where you can check if the person has primarily solo or dynamic climbed. //

TL;DR: Match solo queue players with only solo queue players. Problem solved. Also, remove the 4-man ranked queues.
