It surely dooms smurfs. After the matchmaking patch I’ve seen so many smurfs, who would have less than 20hrs of playing yet get matched with me, with more than 20 win streaks. I’m pretty sure that they are smurfs because they know how to roach, tinkerbell, what skills to dodge and what to take, and how to cut monster off. Very hard to do that in less than 20hrs. Some of them are even friends of players with more than several hundreds hours of playing. (tbh the number of smurfs got extremely larger after the weekend op event, but whatever.)
Whenever I eat them up I feel like I’m doing something good for players overall… and feel relieved that he will have bad time after this point, and won’t be able to bully newbies.
Unless they make up a new account again but it will bug them a lot to make a new account after playing every 10hours, so… I would say the number of smurfs will decrease over time with this new matchmaking system.
