Cho. He's awesome!
honorable mention goes to Budd
1. He is the only non-druid to get the druid flight form mount
2. Kara and Deadwind Pass are still the creepiest places in WoW
Basically a badass priest who lost what he was and did everything he could to retake it, and when he realized he was descending into madness, he bide his time and delivered the master stroke that freed outland.
If there's any justice, he'll make a big showing soon, and not just for Warlocks.

Draenei Rogue. Hopefully a taste of what's to come.
I'd have to go with Tirion Fordring. When I first found him in game, back in Classic, he sounded familiar, but I couldn't remember why. When I realized he was from Of Blood and Honor, I was glad to see a reference to that book. When he came back in Wrath of the Lich King, he merged my two favorite organizations, and repeatedly showed how awesome paladins can be, all without having to resort to any gritty tropes. He lost everything in the past, but didn't let that stop him from being a hero to the world.
I don't like Uther that much since he was totally fine with stripping Tirion Fordring from his paladin rank/privileges when he supposedly consorted with the enemy (Eitrigg). I think that story shows that Uther wasn't very openminded. Also Uther was pretty much a softy when Arthas suggested to purge Stratholme. I mean there was no other choice now was there. The inhabitants were clearly doomed. And while it was a vile job, Arthas was right in doing so. Perhaps not a job for a paladin of the light, but it needed to be done. Now Uther clearly failed at making the hard calls. The only other option would have been to let Stratholme "die" on its own and quarantine it. Which would end up the same and the inhabitants would have seen unspeakable horrors before they fell.
Bolvar on the other hand defended Stormwind for a long time. Fought against Onyxia's minions with zeal. He was THE defender. I have even seen him battle Kazzak when he was kited to Stormwind. Epic show of character when he took up the mantle (helmet) of the Lich King. I never heard/read anything negative concerning Bolvar. Although in the comic he is a bit dimwitted (perhaps by spell) not to see through Lady Katrana's guise. I was gutted when I saw The Wrathgate cinematic. So dissapointed that he "died" that easy (sure he was the last one standing, but still). But still one of the best cinematic thusfar in WoW. His sacrifice shall be remembered.
Connor. Just one look at the guy would make anyone want to kill them self. He would be the ultimate weapon against the Burning Legion.
The ruler of Theramore; the leader of the Kirin-Tor, Lady Jaina Proudmoore
Ridiculous this is... Yes, something very ridiculous is happening in here!
What I disliked (but I don't blame the character for that) is that his voice was so low compared to the chat when he broke out of that ice and smashed/shattered Frostmourne. If he yelled like the chat hinted, it would have been far more epic. I think Tirion Fordring is what Uther should have been if he wasn't that pigheaded. Tirion is a true soldier of the light, while Uther is more of a father figure perhaps.
The one who made Warcraft amazing as it is..... or was.
