I think positional matchmaking is good for ranked

As someone that alternates between jungle and support roles for ranked play, I feel that positional matchmaking will have an overall positive impact on ranked play.

When I play support, one of the things I usually do is look-up my ADC on stat sites to see whether I am supporting a beast or a potato. Of course I would rather get a beast but otherwise I could decide whether to dodge or otherwise play more passively. Reason being, I personally feel that botlane has a lot more technical depth compared to other roles (up to 12 summoner spells and 24 abilities to be simultaneously used when junglers are involved as opposed to 6/12 in solo lanes) that players who sometimes play other roles fail to appreciate adequately. So positioning, especially positional trading is harder to appreciate as compared to solo lanes.

For example I may get someone who is a beast at Azir at mid but doesn’t really understand where to position the wave when he is playing Twitch in the botlane. As a support, I have lesser influence on where my ADC would want to position the wave (if he wants to push I can’t reach through my monitor and strangle him and ask him to stop pushing), so I think positional matchmaking will lessen the chance that I get potatoes to support.
