Please read this before reworking Aatrox
If you guys really want him to be true to his lore, as a Darkin that thrives in battle...
He MUST be good in teamfights!
Please don't rework him into another Tryndamere and pigeonhole him into a splitpusher. Aatrox is supposed to thrive in battle and should look for every opportunity to start a teamfight.
While i'm not exactly sure how it could be achieved, but sacrifices must be done. Even if it means he's actually bad at dueling and splitpushing, he really should shine in teamfights. Remove his ranged harass and give him more tools when surrounded by enemies so he prefers to fight multiple enemies at once. His current passive could go in favor of something that's more teamfight orriented.
Really, i'm pretty sure that most Aatrox players are only asking for this.
