Is it really based off the bracket? Lemme test it real quick. I don’t think it is.

So dampening starts at 30% I think if you face double dps. Then its 20% flat rate for everything else. Ramping up 6% every min. So no matches are quick. It is not based off bracket at all if you mean brackets like 1400 or 1600 its all the same. For 3’s it works a bit different taking longer to ramp up making matches last longer.
You mentioned class tuning. But class tunning has been awful the last 3 expansions. BFA, Legion, and now Dragonflight.
3’s is really imbalanced if I was seeing 3 rogues playing sub going to 2100 + lol. They got a nerf but I’m sure a lot of people skyrocketed.
Not to mention the DH doing insane dmg.
