Rating doenst have much to do with mmr, so you can't really tell which team you are going to be up against since most people probablx don't know their respective mmr. But just FYI, everybod starts at 1500 mmr with no games played.
so with a mixed rating team as above, we could get any (completely random) rating team as an opponent , or with more members on higher rating in my team we're going to be up against higher / better teams and with lower rating members we'll be up against lower / weaker teams in general?
