While I understand the concerns of 'if Dyrus gets one, people will scream that their favorite pro player should have one!' and those concerns are valid, I still want to throw my weight behind this thought of a skin for Dyrus.
It sort of reminds me of, forgive the hardcore nerding for a moment, the Magic Hall of Fame. The players chosen to get rings are chosen not just based on how many tournaments they win, but also to an extent their personality, impact on the game, and what they've done to push the game forward and promote it and it's evolution.
Dyrus has been, from what I've seen, the rock.
He's been that guy you want on your team who's just...he's just there. He's consistent and stoic, at least after a fashion. He may get super-mega-ultra camped, but from what I've seen he's not the type to just afk at base when that happens. He knows what he needs to do, and even if it's tough, he does it for the team.
He has flaws, as everyone does, but I think at least certain aspects of his personality represent desirable traits in a League player. You WANT a consistent laner, someone who's not gonna ping constantly for ganks because the enemy jungler showed once, or because he died once. You want someone who's there, who's your rock. Who's gonna attempt to do his or her job come hell or high water because they know that's what's expected of them, and if and/or when they screw up, they're gonna take that feedback and they're gonna try to improve.
I mean for the love of all that is holy....some of the times he's been ganked and camped? Man...that would break ANYONE. He never seems to break. He seems to just stay strong and do what he can for his team. We'd all like that on our team, and let's be honest: we could all stand to be a little more like the Grand Sensei and take our losses and setbacks with stoicism instead of rage and salt.
Bottom line is that I think a skin for a professional player that has made an impact, and has traits we, and Riot, would like to see in more League players, wouldn't be a bad idea.
