No. No, you didn't need to. There were other dungeons with mythic and mythic+ options. Siege of Boralus and King's Rest weren't the only two dungeons in the game with mythic and mythic+ options.
Wasn't it, back in Vanilla, you had to keep grinding PvP and honor otherwise you'd lose ranking with each passing... week? Or was it month?You have to grind for PvP ranks. You also have to grind for PvP rating (titles, rewards), the point is?
I can call your attempt to pass your experience as a general fact of how guilds operate in BfA. Every guild I've been in has provided flasks and food for everyone, and sometimes even potions. Anecdotal evidence cancels anecdotal evidence.Every guild I've been in, whether it be a Mythic progression guild or a casual AotC guild has required me to show up fully buffed with food, flasks, and potions. My Classic guild has not required me to show up with anything other than mana potions. You can't prove my experience wrong.
