Seriously fun :)
As you stated, this were quite cheap, but so fun it was worth it.
I really enjoy fun songs, and even though I'm not a WoW-fan, I know enough of the game to know what you're singing about :)
And it was really cool too hear a melody I'm extremely familiar to.
One thing I think would be really cool with this song, was if you would make it a Trance/Techno/Dance-ish song of it with the same lyrics. That would seriously be awesome.
Anyways, 4/5 and 8, just because it was quite cheap :P
Otherwise I loved it ^^
And good luck with the girlfriend :)
I just got dumped, so it's nice to see that someone else can be happy still.
Be well, friend :)
