gnomish model bugs. What to do ?

I've been playing gnomes for a while and gotta tell you i faced many bugs that they produce, gnome mount bug etc etc

Ive had this certain bug/feature for the last 2 weeks already.
Short discription:
when landscape changes camera turns onto 1st person view:

It becomes unreal to play on arenas that have upturns/stairs/lifts even the tomb at lordaeron ruins.

you can solve these problems by removing WoD models:
1. Open WoW folder
2. Open the Data folder.
3. Delete the patch-w.mpq file.
4. Delete the patch-x.mpq file
5. Open the enUS folder.
6. Delete the patch-enUS-w.mpq file.
7. Delete the patch-enUS-x.mpq file

no wod models

when you try to cast gnome mount while in a big city (like stormwind) you get instantly dismounted?
