Epics are still usable/meta

Idk why but recently i kept seeing videos about how "epics aren't meta" or "only epic+ cookies are usable". Like i wonder if they play anything outside of arena. Yeah most epics dont stand a chance in arena but their acting like pve doesn't exist. Most guild bosses only need 1 - 2 epic+ heck even the avatar of destiny doesn't even need epic + cookies. And from what I've seen in cookie alliance the hero teams needed the majority of cookies are just epic. What im trying to say is epic cookies are still very much usable and meta. What are your thoughts tho. Thank you for listening to my rant bye
