Interesting ... perhaps i need to fine tune my movement. When I was doing 10 man maly with out a DK we were having problems with the sparks. It would seem the spawn rate of the sparks was faster because I would have a spark spawn on one side I would move him so it would path over the center but then one would spawn on the side I was on and I would be dodging 2 sparks and it would not path over the center area so to speak.
Perhaps dps was not killing them fast enough im not sure. Or waiting to long for what would be considered center. I guess we will find out tomorrow.
If im not mistaken you have a DK in your 10 man video and several in your 25 man video. Do you happen to have a video with out a DK or are your DK's not death gripping?
