EDIT: Does it need to be said how fucking stupid Zyori looks all the time? We get it man, you're a special unique flower, just shave that rat pit off.
I have nothing against his looks, he's free to do whatever he likes in that regard. Just please stop talking during casts and brush up your game knowledge. He has no idea what he's talking about the majority of the time.
i.e: game starts, Merlini smoothly goes over Dire lineup, then Zyori looks at Radiant and has no idea who is who and stalls with a bunch of 'umm' 'uh' 'wow' while he struggles to match heroes to players. You would think spending a good 5+ minutes in the drafting stage and seeing hero picks would help you know that amirite. His camera control is horrid and he generally seems to have no idea what's going on, instead leeching off what his co-caster brings up to keep the discussion flowing.
A combo consisting of Ayesee and Zyori would probably give me an aneurysm >:|
I hate harping on the guy but it's so irritating, especially when there's a good co-caster with him who I'd like to hear.
Edit:
Steve, he's not only a great laner, but his ult gives a team a ton of control during fights. Plus haze miss chance can be pretty good late game. A disciplined team that's ahead in the game and knows how to bait out and avoid engaging until Brew ult is down will always make him look like a bad pick
