Riot is doing something beatiful (right under our noses!)
So recently, Riot reworked some champions..

Notice something common between all 3 of these champs? They all are (or somewhat were) auto attack champions.
Yes i know, they are still pretty much AA champs, but think of it, they added a skill shot to xins kit, they added less AA and more team fight with irelia, and now with aatrox, they are completely removing his AA mechanic. This is good, they are changing champs to be more ability based instead of just boring autos (I know adcs still have this, but whatl can we do? they are adc, its all they have).
Xin was probbaly the experiment of removing brainless right click and button spam from a champs kit, sure they didnt change much but they did make him use more skill!
After Xin, they moved to Irelia with her new Q, W, E and R all being less based around auto attacking and more based on outplay and skill :D
now aatrox is becoming a completly different champion who uses abilities in a fight, basically think of Irelia being the successor of Xins rework and Aatrox being the successor of Irelias rework! :D
All I can say is thank you Riot, keep removing AA from the game! Cough
cough oh excuse me, haha! but you have done good so far on removing AA from the game! Keep going rito!! (srsly tho plz rework tryndamere at the very least.. maybe trundle too.. maybe some others as well..)
Who is next i wonder...
