For the sake of objectiveness i would like to point out that its more about your group class compositions vs class compositions at opponent teams rather then pure archetypes.
Ill give bright example from yesterday -

I was on my lowbie destro alt as duo with friend. That SC started with destro having no healer at all and the only healer joined when it was like 0-300 in destro favor (zealot is 14 kills behind as you can see). However it didnt prevent an absolute stomping of order side with them being able to do totally nothing.
Take into account that order had 2 dps 80+ just as destro and order had 5 healers with 2 of them being 80+ (and rr68 AM topping the charts) and they still got beaten with no chance to fight back. And actually ive got lots of kinda similar pug SCs yesterday (without Teinhala premade in, thats important to note) where destro had 0-1/2 healer and still easily won vs more or less balanced by archetypes (!) order.
What does it shows? It shows that composition in a group is incredibly, very very important. It shows that individual and group actions matter very much, it shows that your strategy&tactics are very important. Im experienced enough to showcase second per second what exactly order did totally wrong and how they could easily win this. But they made enormious amount of incredibly huge mistakes while destro did play carefully, cautiously assuming their gimp comp (no healer), everything to advantages (of having melee ball) and negating the disadvantages (go as one, pull out if focused, dont die for nothing).
So suggestions of alike "dont launch sc if 1 side 0 healer" in vacuum (without many other measures!) will not prevent stomps happening, will not prevent imbalances, will not ease anyone's pain. All it will do is just increase q time drastically.
What will definitely help out:
- copycat ranked UI and show q at least by archetypes so players will make informed decisions
- copycat ranked SC start confirmation algorithm to start SCs and show it in chat similiar to solo rankeds pops so no 4v8 ever starts
Ideal decision is a complex system that will account builds, specs, RR and will have many freedom degrees (aka AI) to create most balanced by those parameters matches while still preventing long q times (=if there is garbage in q it will create garbage match). Thats quite time consuming to make, but devs are very high skilled to create such system.
