WOTLK client with WoD models

Hello guys!

So I experience major issues with client crashing in Dalaran, it's crashing everytime I try to get there, but after relog it works fine for some time. I also just got into Northrend and got a crash on my first run in Utgarde Keep. I also noted that in the character selection screen undeads miss a lot of textures (example), not sure if this is all related. I also tried to download the client again, but the textures are still missing, though I didn't check out the Dalaran yet. I am not sure if something wrong with client itself. I don't actually mind missing textures, but not the crashes.

Please advise if this is really related and what can be done to fix this.

Somewhere here in the forums i read something about WoD models make the client instable. If you dont really really really need the new models just go back to the old models and you should be fine

On this thread http://forum.warmane.com/showthread....hes-in-Dalaran players provided 2 different solution:
1) Remove WoD models by following this easy guide http://forum.warmane.com/showthread....the-old-client
OR
2) use this software: http://www.techpowerup.com/forums/th...-aware.112556/

Oh thank you kind sir!

But why the new client is promoted by Warmane staff then. It could use a tag [experimental] or something. In those threads I see a lot of people having this issue.
