Mages have unanimously been the weakest class since forever
Or at least since I joined in early S2. There have been outliers when a single mage has been broken or offers enough utility read: orianna/lissandra/tf inbetween nerfs to be an important or contested pick but the class as a whole has always underperformed. You see all ad/4 ad comps all the time with mage even being a chosen role just so you can't be dicked entirely by the enemy stacking armor. (esp moreso with ad champs coming out with more utility or enough damage to offset the lack of, also read: assassins) Mages are rarely (rip kassadin) pick or ban. AD has ruled this game for a very, very long time.
I really hope this is their time to shine. You could have said this same thing about adcs because of how they were mainly chosen for quite awhile there because you_ have_ to have someone on your team who can push towers well but they got their upd8 and we all know how they're doing right now.
Idk, as a mage main I'm super excited and worried that'll end with me letdown, but I'm rooting for this MYMU to push us to a point that maybe we even see _two _mages in a single game!! Even though they'll get immediately dumpstered for being relevant. Even a few weeks would be nice!
