I made a video from our 25 main Naxxaramas raid on Monday this is the Arachnid wing sped up a bit to fit it in the youtube constraints. If you set it to High Def you can make it out pretty decently. Gives you an idea what the dps is doing, (like me targeting the wrong mob during Grand Widow Faerlina).
