All my games are in 7th edition, I don't track wins losses because I prefer to eat a lot of food.
I win less than I lose, because I often play people who've played for many years, and I generally play soft lists versus hard ones, until I play in leagues, where last time I was second with around 10 games played to someone who had played 15, and he only had a single wins lead.
There, there's my e-peen stroking done, when it matters I rock. So there.
Anyway, go skaven.
Notice how armies I use a lot lose a lot? 
No. I noticed your daemons win alot. This is not a surprise.
I'm at 100% loss rate for DE! But then I've played like 1 real game. (others were 400 point warbands).
I've only played 3 games with them, won 2, first win was due to a plan working, which naturally wasn't due to ability on my part, but my opponents bad luck

, other WAS a fluke. (doesn't count a ridiculous 4 player game which I wont mention ever again)
