Brain Dead Champions
Just wanted to get this out there, we here the term brain dead champion a lot in LoL. So many people get so offended when they hear the term too. I just wanted to say when someone calls your favorite champion Brain-Dead it is not ment to be a personal insult vs you... its just ment to describe a very simple champion. Some Champions are very basic in comparison to others so the term brain-dead is normally used to describe simple Kits that tend to play themselves out.
For example if someone says Nasus is a Brain dead champion, they are not calling you the Nasus player stupid or brain dead for picking him... they are simple trying to explain that the champions kit is extremely simple to play. I mean look at his kit... Passive(Soul Eater) free life steal , Q(Siphoning Strike) AA reset W(Wither) Exhaust but with further range, E(Spirit Fire) is probs the hardest part about Nasus kit and this "skill shot" is gigantic and E max Nasus is pretty strong because of it. You can press these skills in any order as fast as possible in a fight and actually do well, His Ult(Fury of the Sands) is also very simple.
When you compare this champion to something like Azir or Ryze he is very much Brain dead... just remember you are not Brain dead for picking him so don't treat it as an attack on your personal character.

is pretty braindead because he hasn't got one... and soon, neither will you
