I've heard that too. I've been meaning to try and get the flawless raider trophy from doing it; i think that's what it's called. Anyway, thanks for replying. The rep will probably collaborate what you've said. I'll just have to keep hunting them as have almost enough ogre kills to get the glimmer bonus. I'm sitting on 3375 grimoire score so, it seems like I might as well finish what I started.
