I don't know if this was asked about Skarner before but

There will still be one crystal in all the same spots.

In a mirror match, the ones closest to your team will spawn with your skin's effects.

In all-for-one, they will be mostly random as to which skin they choose.

Can I ask a somewhat irrelevant question, is there any work being done to Aatrox? He's my favorite champion and his kit feels really clunky and poorly designed so I was hoping at some point Riot could rework him, even if it is next year or something.
