Skarners actually good
I just played Skarner for the first time (second if you count being barely level 30 and stopping world hunger) and he's actually pretty good. He's got good damage if you can get a sheen, tanky with CC and SUCH good clear. It honestly makes me wet how much farm I can get and so fast as well. I really don't understand why people say he's bad and he's so underplayed.
