It sure is. And your defense wasn't bad. I'm no top tier player, and never will be, so I wouldn't really know anyway.
My current defense is Edward, yeah. I was going to switch back to a normal defense, but kept running in to people with weak D's, so I kept it. And I kinda soared in the ranks for a few days, haha. Now I'm back to normal, sitting around rank 1200 or so.
