There was Idra, what else do you need?
I watched a couple of games but they were pretty boring. I guess I'm biased since I don't really like playing the game myself much but I can still watch League and enjoy it, HotS so far I've found to be pretty boring to watch. Lack of like, personnal stats and stuff maybe. Like you can't check the "top lane duel" or how much cs that Terrorblade has at 30mins, so it feels more dull. Yay teamfights all the time but like no power spikes in them, like you know, oh shit that AP guy just got his deathfiredagonthingie or Ogre got his agh, next teamfight is gonna be way different now, it's all kinda the same once everyone has their ults. You get abilities upgrades and while they do have a noticeable impact on personnal performance, I don't feel they have as much of an impact as a big item pickup right before a teamfight(especially in dota, stuff like agh or bkb can change a teamfight entirely).
So yeah I guess the reasons I don't like playing the game also bleed into reasons I don't like watching the game. Didn't help the players looked awful, but then again it's hard to have a good tournament when your competitive scene is at the moment completely strangled by "design" decisions due to the early state of the game(stuff like not having private game for a while and still very closed beta).
