I've seen way, way worse?
It depends on what the win rates are
This seems stable. Not sure what's the problem.
That level 30 is always a wild card. Could be better could be worse. You probably wouldn't be complaining if you knew that level 30 was a platinum 2 smurf.
And there have been matches with even more disparity. Like when you get a team ranging from Platinum 4 to Platinum 2 going up against a team that has 4 Bronze tier players and 1 gold 5 player. Those matches are far worse.
