Game CRASHING while in Wintergrasp Battle

[RankDoesMatter]

Hello, I have some problems with Wintergrasp. I'm sure i'm not the only one and I hope someone has a solution for this. My WOW crashes in almost all Wintergrasp battles, which makes it too hard for me to gather Marks. Is there a way to fix this?

My computer is fine(8GB RAM, Intel Core 7 2.60 ghz, AMD Radeon R7) It should handle the fight without problems.
I have heard that the way to fix this is by lowering the camera distance + lower the max view distance. I have lowered EVERYTHING to minimum and still the game crashes.

I am using the new WOTLK client that warmane offers(with the character designs from warlords/pandaria). Should I try the old design?
If you know something please help.

Most likely WOD models cause the game to crash. It's a known issue.
