Are we ever going to get Team Matchmaking for CC?

[Karasio]

Alright, let's start with the "fracturing the community" part. So you're scared that people who are currently solo queueing might go off and play with their friends instead, leaving you alone? How can I infer this to be anything but seething about being friendless? If those people do move over to team queue, then clearly they never wanted to solo queue in the first place - And now they get to play what they wanted to play all along. You're also running off the laughable idea that PvP can never gain new players - Anyone who goes to team queue must be coming from the existing solo queue community. Have you not considered that there are people who avoid PvP right now because it's not a social activity? They can't play with their friends, so why bother at all? Where's the fun in getting randomly grouped up with and against faceless nobodies who you will neither know nor care about, and never see again?

As for your "I have no idea how team-based pvp has ever worked in this game" - Do you mean to imply that the PVP mode based around team coordination, with massively support-oriented jobs such as Paladin, Bard, Dancer, Scholar, Astrologian, and Sage, would somehow be worse in a coordinated environment than a quickchat-spamming clown fiesta?

Based.

Player retention.

Solo matchmaking in general will not suffer as badly as people think it would because it is numerically and statistically easier to create a match of 10 solo players.

Team matchmaking (I assume this is 5v5 premades-matching only) might suffer from similar effects of the The Feast Team season back then. Lesser skilled teams will feel bummed out by stomp-teams, lowering player retention and shooting up the queue times.

Full-team matching is difficult to implement and I doubt the community's heart and attitude are in the right place to handle such a mode well. That said, watching full-team matches is an absolute banger.

Short: Team matchmaking would struggle to keep player retention unlike solo queue or dynamic queue.

I'd argue in favour of something like a flex queue that League has with much more lax matchmaking, but that would mean that intern-san would actually have to work on PvP for once LMAO. And they'd have to implement some kind of an ELO system or something.
Unless that's what you meant by dynamic queue, in which case I totally agree with you.
