Alot has been said about the MM changes introduced in patch 9.18. Both good and bad opinions were voiced and discussed at length. Personally I like the new 3/5/7 games since being low tier doesnt mean facing 12 top tier tanks anymore and Shooting higher tier tanks gives more XP. Being low or mid tier alot is expected since only 3 out of 15 tanks are top tier in 3/5/7 matches. Add the uneven distribution of tanks per tier in the MM queue and you get problems like the constant bottom-tiering of T8s and the good MM for T7s. (Discussed here)

Last night I platooned for the first time since the release of the patch.

Oh boy, is MM fucked for platoons.

I gave Little heed to this thread's part about platooning since i mostly play solo but friends were online and I was in the mood. I can't remember how many games we played at tier 8 but in a couple hours the best MM we got was bottom tier in a 5/10 game.

3-man platoons obviously have an exceptionally low chance of being top in 3/5/7 games since they fill all three top slots. Being matched against 3 randoms not in a platoon will also most likely mean a dominating victory. But right now platooning below tier 9 means being bottom tier pretty much all the time. Which sucks balls.

What if we bump it up to tier 10? Surely we'll be top tier against tier 8s then? Oh look, suddenly we see single-tier T10 games exclusively.

Maybe Special MM rules to match platoons against each other is needed?

TL;DR: The new MM is seriously flawed for 3MPs, leaving you bottom tier almost exclusively.

Edit: "bottom tear". hehe.
