Virtually Every Change The Last Five Patches Have Been Direct or Indirect Nerfs to Mages
I think this may be the first time in his history that my main boy

There's been too many changes in the last few weeks that have destroyed immobile mages like Vel'koz, whether that be buffing their counters, making their runes / itemization less efficient or changes to the way the game is played like Baron-empowered minions being literally impossible to kill for anything with AP.
You've really screwed the pooch this time. It's time to start buffing immobile mages.
