Was against the idea, too, 4 the same reasons. However, i didn't notice a match starting with uneven numbers of players in excess of 1, but another weird thing occured 2 me - i've been switched 2 the other team - either accidentally by pressing the key 4 volunteering (what i don't believe), or have been FORCED 2 the other team several times 2day - not sure, what happened exactly, but after the switch the teams were perfectly even again by numbers.
Maybe they decided 2 allow the matchmaker 2 automatically switch a player of his choice if needed? I'm really curious about that, too, but i guess in any case mentioned here the devs would let us know about such important changes in an official announcement, anyway.
I also noticed the usual disbalance kept 4 many matches on several servers, although the matchmaker mixed the teams anew due 2 leavers (at the end of the match) and others that joined (at the beginning of the next match). It just stayed disbalanced, although it looked like the matchmaker is doing its job well -
it separated the equal number of equally skilled players (which i know well) in2 opposite teams, as it's supposed 2 do, but the balance kept broken, obviously. I can only guess, that there were some smurfs among the "noob" players (that i didn't know), that lead 2 the disbalance, but i have no proof of that...
I think, they should simply open up all servers 2 any1, regardless of his/her MMR just 4 a short while, 2 let us c what happens. Maybe that's an improvement over the current state. If we r not able 2 try out, we'll neva know...
