I have serious concerns about the accuracy of that last parse. For starters I'd want to know crit rate (should be around 5% if they were only using rains, separate the pets, otherwise it will take those into account). I'd also want to know whether monster summonings and/or host of the elements was used (many raid encounters they are next to useless due to ae's and whirlwinds fucking their face right off). I'd also like to know why and how your warrior was doing competitive dps with the mages and rogues. I'd also like to know why there are 4-500 less hits on the rogue than on the warrior. I'd also like to know why your wizard was only engaged for 57 seconds (I'm assuming death).
Since that fight was around 9+ months ago, I can't recall the specifics, but the warrior's DPS (Nilaat) was definitely padded by inclusion of his damage shield. Monk/Rogue DPS was affected by breaking off to kill adds (usually Cilulizi or in some cases myself). Overall, probably not a great fight to compare DPS when mages are focused on boss but other DPS not as much.
