More Information On Aatrox's Future Changes?

I was thinking the community could get more insight on Aatrox's changes that will be coming to the rift later on. Currently I'm itching for information on what they are going to do to him like anyone that is having their main champ changed would. I've been planning on ways to get him to work in Platinum elo but I ended up dropping from Plat 2 doing so but managed to climb back to Plat 3 eventually.

OH and will this change be coming in late season 6 or season 7?

Hopefully you guys make him better than before :) looking forward to it
