Here's the current leaderboard, Squishvegan is their name (and #2 in the world is their alt lol). If you go to their profile, they have links to dominion and other vegan resources.
Idk why I'm making a post about it, just thought it was really cool. Most people I run into in any game start acting weird if you even hint that you're vegan and this person is just yelling from the rooftops about it.
probably for more chances at ideal gear from the vault at the end of every week (lots of high level players have alts with the same class and spec and they play the one with the most luck on getting gear)
e: also seperate raid lockouts
that makes sense
