I'm pretty sure this goes along the same lines as what Joker is saying....

And,

I don't know about you, but I’m pretty sure there are an odd number of players in the server just as much as even on any given day when the server is not full. Also as he pointed out, 20v21 has nothing, to do with the teams being stacked. Whichever has the better players who work together, and taking into consideration of what map you are playing on ( If the map is sided towards one or the other )
And,
I have a feeling people are complaining to complain at this point by blowing it way out of proportion.
