Battlegrounds and LoS

Seems like Outlands battlegrounds have completely broken LoS. U cant hide behind any object keeping receiving damage through any kinds of textures. And 2 bugtracker reports just dismissed.

WTF is going on? Same **** happens on arena? Because as far as i can see world LoSing doesnot work as well, mobs in Outland completely ignore textures and u cant hide.

Sadly LoS worked like this in TBC.
I already suggested to implement the improved Wotlk LoS mechanics also on TBC but nobody seems to be interested in this.
