This kind of discussion is not new. There are alraedy multiple threads about some tool to balance teams in the lobby. Call it ‘show unranked ranking’ so players can balance the teams based on that ranking or call it ‘A ranked lobby’, so you can balance teams based on the current MM rankings or call it a feature of the game as ‘auto ranking’. For me it is all about the same. This is already discussed in for example:
In previous games/platforms (HD, Voobly, … ) there was no tool to balance teams. It has to be done manually. Now in DE they introduced matchmaking to have balanced teams and even balanced 1v1s. It is great we now have such tool. I wont say it is perfect or is usefull for every situation. I would much rather have focus on expanding MM so it is better for more players, than having a second tool to balance teams, a tool with its own drawbacks. I much rather have 1 great tools, than 2 tools and every think meh about tool.
