Yeah I never said you said those things, I just pointed them out.
Right so I had a long post written about how to solve all the issues Blizzard mentioned (and a company as large as Blizzard should've already realized these solutions are good enough):
- Brackets? Separate. Only allow duo q if they can manage to implement some system where you lose less mmr/rating if you lose to a duo q as a solo q group.
- Titles? Create separate end of season titles + new highest spec titles seasonal achievement + solo q-only rating achievements.
- Communication? Implement battle.net chat into solo q, or just let it be and let solo q develop its own meta where good solo q comps can thrive.
- Comps? Let people select what comps they want to be matched as, and only match them as those comps (say a minimum of 2 comps). That way no one can blame the matchmaking, and everyone is happy. Bad specs will have longer queue times and will thus get more attention from Blizzard and get buffed faster. Make it impossible to request comps with tanks, class stacking and double healers.
- Queue Times? Anything's better than 2 hours LFG only to have people leave once you lose first / second game. Although I dont personally suffer this problem as I have friends to play with (just barely though, many left) but I've heard lots of stories from others.
- Toxicity? Hardest one, better report system on scoreboard screen is required to begin with. On top of that GMs dedicated to cleaning things up and
very harsh punishments for bad behaviour (mute in solo q, mmr loss, deserter for up to entire season, disqualified from end of season rewards etc) would alleviate it a lot.
