I'll start off with one of the biggest flaws of the game in that I never really connected with the Protoss. The Protoss are an interesting faction but I've never been drawn to them because they seem so stoic, grandiose and entirely unrelatable. Protoss are like a race of...

John de Lancie!!! I can't wait to hear that one!
I think in the end, I'm more of a Terran player. I like the Siege Tanks and the Battle Cruiser. I also LOVE being able to call down a nuke strike with Ghosts!!
I only slightly disagree with you here regarding difficulty. I've found LotV to be a challenge, even on Normal difficulty. Maybe it's because it's been a while since I've played any StarCraft. I've actually looked up some help on most of the missions.
Also, I'm having a video issue. It's hard to explain. I just finished helping Raynor and got the...what's it called again? Crystal? Rune? Something like that. When I freed the big ship and was able to select which planet to visit, I went for Korhal. So, I just finished those two missions. I went back to the Bridge because it said a conversation was available and Artanis was talking to a Terran, but because of a video glitch, I couldn't see his face. Something similar occurred before and I think it had to do with a shadow.
Also, take a look at the picture below. The panel on my Blizzard.net looks funky after I play the game.

Yeah, have you checked out updating your video drivers? Beyond that i'd look at the Blizzard tech support site, i've never seen that personally.
My drivers are up-to-date as of 12/21 at about 8am. But, yeah, you're right. I'm not sure how to get a screen shot in-game, which would be helpful to show Blizzard tech support. I could probably find out though. I do wish the game had an in-game browser like Steam, though.
I finished LoTV a month or so ago and I thought I'd share my experience with you, sorry this is so late. I'll be completely honest with you, I found it to be a bit challenging, perhaps a little too much for my taste. I know I could have turned down the difficulty, but I didn't. I was hoping to get those Normal Difficulty achievements, although what I'm about to tell you contradicts that. There are a few of missions that I decided to cheat on. That would be the last one in the main quest line and then two of the missions in the epilogue. By the time I reached those missions that I cheated on, I was ready for it to be over. I'm not saying it was horrible, but the difficulty was frustrating and I wasn't enjoying it very much. Two of those missions were VERY difficult. The last one in the epilogue with the Zerg, I decided "f" it, I didn't feel like continuing with the challenge.
It took a little while for me to get used to playing SC2 again and with the Protoss, but I managed to get through most of the missions on Normal difficulty without cheating. I often made as many peons (those things that mine minerals) as I could, that was helpful. I often used the ship's ability to harvest vespene gas for me. I enjoyed some of the other abilities with it, too. I did enjoy some of the units, in fact I think I really liked many of them a lot.
Anyway, I just thought I'd share with you my progress on the game. Like I said, I'm sure it's been a month or more since I finished it.
I totally agree Greg, those missions were really hard and required me to play them a couple times to actually beat them!
Thanks for sharing. What did you think of the trilogy wrap up and such? Are you getting the new Ghost missions? I still need to pre-order those.
Well, that one character died in the beginning, that was unexpected. It'd be a spoiler to reveal his name, I think I remember it. I liked the John de Lancie voice over, that was cool. I liked how pretty much all the factions needed to come together. Ok, that's a bit of a spoiler. LOL. I liked the ending, I think. I liked that the two Terrans were reunited, one, it seems, was granted salvation.
I pre-ordered the new Ghost missions about the time I started playing LotV. I'm hoping they'll be more fun, kind of like when you control certain named powerful characters. I'm not sure if I recall any of those missions in WoL, but I believe there were some in HotS. There was at least a mission or two where you did that in LotV. I'm sure you know what I'm talking about.
SPOILER ALERT GREG!!!!
I liked the ending too. I felt it was pretty solid and a nice way to wrap things up, which I didn't expect I am sort of used to bittersweet endings and this one was actually really satisfying. Again, so much so I wonder what's next? Everything seems fixed. But there are Taldarim, maybe they will be the new bad?
