To me... going back to 5v5 is a step backwards and ruins my game experience.
Of course a full 8v8 match of only human players is the best option. But look at the score board of a match I had on Tuesday and tell me in all honesty that these kinds of matches don't ruin your game experience!
And to clearify one thing: I never called for 5v5 as the new default team size. Instead I suggested that 5 players should be the minimum to get a match popping which is an important distinction. As the graphic shows bots don't serve any meaningful purpose in this game anyway, instead they're useless filler at best or mindless cannon fodder at worst.
