I try to stay diverse as well, only being capable of playing a handful of champs and blindpicking a sensitive position like top or mid, with a particual champ just because it's your favorit champ is a good way to get countered and suffer in lane.
And I don't like to play lanes that are stacked against me.
Take Tryndamere, whom I play alot, is quite out of meta for obvious reasons, but that doesn't change the fact that you can easely stomp alot of meta picks with him, I thoroughly enjoy when someone picks Yasuo mid or Irelia top, essentially it's a free win for me if I'm allowed to lane against them and given my team doesn't throw or feed too much. Ironically alot of people seem to suffer against said champions, so while meta and overtuned champs might be prevalent they do acutally have counters and counterbuilds, at least most of them.
Something that disturbs me though is that alot of meta picks are so extremely safe you can basicly blind pick them into and against any comp and profit, I'd call Vayne and Tristana prime examples of such picks.
What get's me though is that alot of people here in gold don't seem to have any clue how to read a matchup, I've lost count of how many times I've had a teammate counterpick themselves when picking in champion select against someone who blind picked a sensitive pos and it always tears me up when they insist on doing so because I know for a fact that they will feed, they never fail to do so, it gets even worse when they start flaming the jungler and killing team morale, after a certain point I'll just mute them and play for the kdr since victory is out of reach anyway.
As for Skarner, is your issue that he always is banned nowadays?
