I bought it because I like it and I play Trynd fairly often.
Why, though, did you post this:
In commemoration of the Season One Championship at Dreamhack in Jönköping, Sweden, we’ve decided to issue a very special limited edition skin for everyone’s favorite Barbarian King. If you’re attending Dreamhack, be sure to stop by the Season One competition area to pillage a code redeemable for a Viking Tryndamere of your very own.
That's kind of false advertising, honestly.
I had this experience with Whistler Twitch. I regret not buying him, so I bought this skin as fast as I could. I could have waited on the cash and picked it up later, which would have been nice.
