If you think Conqueror's on Ryze and Cassiopeia is bad, wait until Azir players pick it up.

Azir's W attacks do not count as auto-attacks but as spell damage, so they can completely bypass the ranged restriction for Conquerors, since Abilities of any kind also give 2 stacks, regardless of melee and ranged, allowing some of the fastest stacking that this game can offer.

Azir can build Conquerors to 10 stacks really easy thanks to that and considering he has really good damage, the healing also gives him some busted sustain ontop.

Not to mention that he has some high AP scaling, so the stats Conquerors gives early are not to be trifled with either.

I am just gonna lay it out as my own opinion: If there will be an abuser who will be responsible for the Conquerors nerf, it will be Azir.
