I am looking for the best combat routine in a high level PvE raid environment (think heroic). I run with very high fps and a very low ping.
Anything that doesn't have hard casts seems a bit more flexible to me. I think the biggest DPS loss comes from having to interrupt a cast to move on a mechanic. I'd probably vote a melee or hunter since they can simply freely move while DPSing.
as dps id suggest warrior both arms and fury (mostly fury) using Fury unleashed Mage using Portal ..i tried frost and fire both seem to do fine Hunter using Yourraidingbuddy Shadow priest using insanity as a healer id suggest leaves for a resto druid ... and oracle for any other healing class/spec for a warrior tank fury unleashed is good aswell and yourraidingbuddy is also good for both brewmaster monks/blood deathknights those are all from personal experience i hope they help you out but you really need to add warrior to the pool so i can vote on that xD
