Blizzard recently opened the gates on a renewed version of an old World of Warcraft expansion, giving players the opportunity to blast through familiar quests and dungeons with way more power than they had back in 2016.
For many players, WoW Legion Remix is an opportunity to collect achievements and cosmetics they previously missed—or the new ones Blizzard added on top. Many of them require completing raids and dungeons that take full [[link]] groups, but finding parties has proven to be a problem in the early stage of the event.
A DPS is rumored [[link]] to be doing M+ in Remix from r/wow
Tanks were on top in Mists of Pandaria Remix too, and it seems like many players knew this would happen again and planned accordingly. A quick glance at the leaderboards for the top solo clears of Mythic+ dungeons makes it clear that no other role can match the raw strength of a tank. This is likely because of their massive survivability and decent enough damage output against beefy bosses.
Everyone else is stuck waiting in long queues, praying that someone who isn't min/maxing their way to completing the event actually chose to play the sub-optimal roles.
It's possible future stages of the event will bring the power level of healers and DPS classes up enough to complete everything solo, but it's a little sad that they don't get to enjoy the fun this early on. Blizzard has been quick to fix the methods players were using to accrue item upgrades super fast, but it hasn't made any comment about trying to fix the severe role discrepancy yet.
