Just lost 2 points of MMV in solo because there was an 0-6 heals in lobby @50 cr.
Stupid system blizzard. Stop giving spots in lobbies to people who have no business being there. The carry over system is one of the main factors that cause rating deflation.
I’m ok if MMV stays neutral on a draw, I’m not ok losing points so little Johnny trashcan that probably bought duelist last season can q @ 2k fresh in a new season and be an ELO vampire.
Why not
a 3-3 stabilizes you as you’re going even, meaning that if you’re been going negative you’ll gain mmr and if you’ve been streaking up then you’ll “cool down” and drop a bit of mmr
MMV is solo. MMR is reg 3’s. This heals literally stood out in the open all 6 lobbies and soaked ccs. Can only grip/swap/md/fear/silence/stun so many times.
0/10 troll. Not bothering with you as you’re clearly an idiot.
That’s a go next angle. 
Working as intended, etc.
Only true if one of the dps are physically playing that character as well. This heals was so bad that a Boomie,Ret,Spriest using cds at really good times (on burst while our heals in cc) couldn’t carry. There is also the fact that everyone won with the other heals doing the exact same things. Which is why you are stupid and this is a bad troll.
No refunds queue up
100% not true. Depends on the bracket because no healer will ever go 0-6 if I’m playing at 1600. I simply would not go 3-3 there, but what the OP is complaining about is a 0 cr healer going 0-6 at like 2100. There are many games where there’s little a person can do at that rating with a fresh cr healer because the other healer knows enough to not throw at that rating, against a possibly rusty, no gear, healer.
if you go 3-3 with someone worse (lower) than you, you should lose mmr
Just wait for the last seasons Elites go come back at the end of this season to queue solo at 2400mmr in full greens and 0cr 
I’m not completely sure how the whole system works behind the scenes but I am sure that there is a severe lack of healers and the optimal rating difference at which a lobby would bring in a healer just to fill the spot is debatable.
People don’t like waiting in queue for 2 hours but they also don’t like losing when there’s someone that clearly shouldn’t be there (whether too high rated or too low). Personally I’d rather go 3-3 and lose 2 rating than sit in queue for that long.
