I don't see why people are having huge issues.
People complained about solo/duo que back then for not fairly representing player skill because of all the variables you can't control. Fast forward 2 years, people are complaining about DQ for similar-ish reasons.
My own 2 cents: neither system is perfect, both have glaring issues, as well as perks. I also like the fact you can declare what role you feel you want to play. That was endlessly requested, however shot down just as often because it enforced a meta.
People will always complain, and while the complaints I've been reading are valid in my opinion, they're also nothing new.
I do kind of wish I could just lock myself into one role and accept I may have a super long que time.
