Savage or hard content it's never going to be added in a random matchmaking aka roulette.

Seriously nobody likes to wipe 20 times in a row just to figure out a mechanic, let's be honest for once , every hard/ Savage content demands a full strategy guide (YT) because that's how SE thinks hard stuff should be.

Everything will 1 shot you.
One party mistake = wipe.
One role not fulfilling properly = wipe

There is no a middle ground.
