We have actually stated it numerous times and have admitted that having more than 1 CV in a match is not what we WANT, however, because que times would be EXTREMELY long, they were the way they were. And we have been working on MM over the past year making changes to mitigate a lot of the issues. Triple CV games do not occur anymore above tier IV UNLESS the que time exceeds our maximum limit to start overriding rules. Recently we've made changes to lower the chance of double CV games and they have been reduced. And coming up we have ANOTHER MM change to lower the chance of double CV matches even further and make MM more ideal for players that could be up-tiered.
