Dude, you’re high plat/diamond. You’re just not going to get placed in Bronze, there is no way. You’ll get mid-Gold at the minimum. Drifting 500SR isn’t actually that uncommon or that big a deal.
I rarely got to DPS, always played Tank, but I can still hold my own at this rank as DPS and Support. It’s just a joke to pretend your differential between roles will ever be that much. It simply will not happen, it’s a totally unrealistic scenario.
