“We’ve talked a lot about rare spawns and their fun vanity loot in Mists of Pandaria, but there’s another reason why you want their loot as well–they drop high ilvl gear with low level requirements. This gear is perfect for making a very powerful 85 twink…”
Nothing in that aligns with your claim that groups of people levelling through brackets as FotM classes were a catastrophic deal, as you’ve implied. If they were ever a thing at all…
And twinking at 60/70/80/85/90/100/110 are totally fine. Those are the levels to experience the expansion of that time. I had a blast doing BC as a 70 twink.
But should I have been in PvP queues with levellers? No. I’m glad I wasn’t. And I did get BG queues just fine.
