Who says only Method can do it? I’m not watching the clickbait-y video by the way, those aren’t typically well liked around here, especially with that particular person in them.
They got the world first. So unless blizzard fixes it I’d say it is okay. If they did this in the race I’d presume it would have been an instant fix. To me this is no different than an all elf, gnome or druid raid. Sometimes people do stuff just for fun.
Then they wouldn’t have gotten World *2nd. There’s a big difference in taking 20 heroic geared tanks into mythic and taking 30 mythic geared tanks into heroic.
It’s not an exploit, they’re stacking 30 tanks with specific essences and corruption and it’s allowing them to clear raids without dps or healers.
This is not exploiting the game, this is playing Blizzards game breaking corruption.
They used a buff that exists and effectively stacked it, using it exactly how it was intended to work.
If it’s truly an EZ mode exploit, I’ll be over here waiting for all the guilds struggling on normal to post their 30 tank Heroic clears by next week.
