Ultimately teams do get rws balanced right

And we all know rws has its limits, especially if new players (given 8.77 rws, but is either doing much worse or better) or when players with stats from Europe or Asia are around (Rarely does the same due to ping).

With similar rws each side you can have stacked teams pretty easily with the buddy system, just buddy the lowest rws player available, you'll get the 1, 2 or 3 players (depending on overall rws) you really want.

And that's without considering that pugs without players leaving became extremely rare, meaning you could simply pm your buddy's when people leave to get stacked pugs on command.

Etc.
