Lordaeron - Cast animation

Greetings.
I'm not sure if it's the correct place to report this, i read a report by somebody on Bugtracker but its Dismissed.
I want to ask you if its just a general bug or mine.
When i play with caster class (as mage for example) and i start to cast, the spell should go out from the right hand, but I use the left hand.
When i cast Arcane missiles i extend my right hand but the spell goes out from left hand. Also when i cast Cone of Cold, the spell animation doesn't go head-on, it goes (as Undead) to the floor at your feet.
I'd installed the Draenors Textures patch.
So i want to know if it happens all of you (Maybe it's a Draenor Texture patch bug)
Thanks.

I'd like to bump this, because the cone of cold bug is really annoying
I have standard texture patch.

what to do?
