[2021] Ruined skinline has been confirmed as canon

So, turns out Viego really did capture Karma, Shyvana and Draven.

While I was a bit torn initially, I like that they are advancing the plot through skins.

Their skin bios indicate they weren't killed, but they were 'ruined'. In other words, they are corrupted/possessed by Veigo and it's a situation that can (and hopefully will) be reversed.
