I can't begin to tell you guys how difficult raiding was this year. I know its suppose to be but on numerous occasion I have had players in various roll who contributed to raid wipes because their PC was not keeping up with the demands of World of Warcraft in a raid environment. I'm sure the same happens on Battle Grounds also.
I had a season where two people that were tanks finally admit to me that their PC was stalling and a DPS who's wifi was not keeping up with the demands of the game. Raiders need game PC!!
What I like to see is a addon that would take the latency & frame rate output of each player and have it in a list that can be displayed in chat. It would be a good tool to trouble shoot players who are having these problems. It might have an adjustable set point of 30fps and have it display the frame rate and the time line of the persons who fall below that set point. The same could be done for latency.
I think a Raid/BG tool like this could improve those encounters for everyone for the next expansion.:)
