Everything is fair in the league of legends right

Just played a match where the whole team besides me went thunderlord thought this was weird then I get killed by a zed lvl 5 because he hit me 3 times and once it proc i was dead. i was yas and did windwall the q all he hit was e and 3 autos. but yet why is everyone going this its way to broken. new level of tilted. Rito nerf before season 6 of league i don't want to deal with that.
