Downgrading from 5.4.2 to 5.0.5

[Darthenn]

I didnt know where to post it so i chose this section since it kind of fit the most. So i'd like to downgrade my MoP from 5.4.2 to 5.0.5 is there any way to do that? i've googled a little bit and i didnt find anything helpful about that version. thanks

Umm, why would you ask that here? since we're playing 5.4.8...
