Personally, I wouldn't enjoy playing with a bunch of other people who are tryharding or are toxic, and theres no way I can convince 5 friends to play regularly, so there's no way I would enjoy ranked. Its bad enough as it is.
I've played one game of ranked and everyone was on their best behavior. The other team even paused for someone on my team needing to restart the game a couple times.
I've played 4 ranked games so far and they haven't been that different from casual games tbh. Biggest difference is probably more comms and more focus on teamwork.
The only communication I get on normal games is russians screaming in their mics and teamwork seems to be the duo lanes feeding Shiv so he's 12/0 at 5 minutes, so I'm taking anything that can slightly improve that
I'm probably going to be splitting my time depending on how I'm feeling that particular day. I'm not going to be attempting ranked matches if I'm tired from sleep dep and feeling like I can't focus, but I am very interested in higher match quality and hopefully better matchmaking. I'm also very curious about how this experimental ranking algorithm will work, so I'll have to at least give it a go. If they've managed to alleviate the immediate negative emotions of instant -MMR after a loss then that would be huge.
It's almost as if they're testing many waters in this alpha game before they commit to a system.
Yoshi on the forums has also created a thread for people to send the match IDs for unfairly and/or weirdly balanced matches so they can analyse in detail
