Dota 2 [ Steam ] has been through a small evolution in the matchmaking to hopefully improve the experience for everyone.Everyone who wants to do ranked matchmaking now has to have a verified phone number on their Steam account. Accounts cannot share a number and free services available online for it are blocked, so this will help reduce troll accounts for sure. You can't simply remove a number and attached it to a different account, as it will give you a three-month waiting period.An older feature for solo players has returned: The ability to pick if you want to be matched against only people playing solo.Players frequently dumped into the low-priority queue for being toxic in some form, will now get longer bans if they are repeatedly in the low-priority. This is a change I personally like, as it will help to stop crap behaviour in a rather terrible community.They also added in some form of detection for bot accounts and issued permanent bans for a large number of accounts found with it. They also added better detections for people intentionally throwing games ruining the experience for the rest of the team.See the full changelog here . I really like this update, as someone who has put 500+ hours into Dota 2 I always want to play more, but the community constantly puts me off.
