Is Aurelion Sol worth it?

Aurelion is an actual skill based champ

He's not like zed/talon/kat who punch the keyboard and get a kill (Yes, higher tier players of these guys are actually good at them)

The difference between a good Aurelion and a bad one is maaaaaasssive

But if you put the time and effort to actually learn/get good at him, sweet jeeesus he will solo carry

Depends on your play style. I'll say this: Aurelion Sol can get jumped on and destroyed if he's not careful. If you want a safe mid champ, I'd consider Akali (if you're good at deception), LeBlanc, or perhaps Katarina.

she can do anything

Aurelion Sol is really weak right now, he's also the most dull champion in the game to play

Ekko is never banned but is top tier, a really good champ to pick up

Aurelion is very potent right now and if you have a macro heavy play style he's very fun because he leans heavily on that.

Just beware; he has extremely hard matchups against most assassins and divers who can get in his face in lane.
