Technical Client with new models not working properly.

[Wak1]

Oke so i liked the idea of wod models on wotlk so u created client, i downloaded it yesterday.
First what i saw was that my DK's face was half dark(black just blue eyes are seenable).Ignored that thinked maybe its like that on wod(dont like it!).
Last night i wanted to raid with friends but my fps was like 20 maximum and avarage i have 50-60 in raids.
My macro's dissapeard its np i created new ones, but when i relogged the old ones started appearing so i had doubles and i had problems on action bars
cause of it its like they stacked since the spot was empty so my good spots for keybinds dont work atm.
I got pissed i left game.
And today 2,3 hours ago i wanted to play again the new client and i wanted to check if they added water textures to the client.
So i got on my flying mount started flying down from Dalaran and sudently everything dissapeard water,trees most of textures and my action bars and spells. I do relog and bam wow error.I log again,again the game crashes and it continues every 5 minutes.
I didnt see any topic like this so i guess its only me but any idea can i fix this or shall i return to old client?
Thanks for reading and sorry for my bad grammar.

Best bet would be to return to the old client, cause to me it seemed like the WoD model client is still a work in progress
