Something I still don't understand with Glaurung is how his pool in competitive has been historically low when he's playing more than 3 heroes on stream regularly. He's been playing nothing but Dehaka and Alarak lately. I know he has no confidence in his Thrall but it's hard to imagine he hel his comp pool low for lack of confidence.
It's possible Denial simply pigeonholed him. Or if there was overlap they preferred iDream or whoever and didn't give him the shot, and maybe iDream didn't want those heroes to begin with. Hard to tell. In more than one way I wouldn't be shocked if he's a victim of his own reputation, both in the way his team frames him and the way the opposition does.
