Ahh the memories, <3 my 2008 OP
The main point of the thread back then was the imba in single target damage which still exists meaning rouges do lower single target dmg than the AoE Mage classes which is wrong imo.
I disagree though that parses are no longer relevant in T3 and above because they show how well each person (not class) has applied their damage to the situation. I allows you to spot patterns and gaps in dmg between the same class and allows you to find the 'sweet spot' for each fight that evey class should learn.
Sweet spot is how to be the most effective you can be, as a ToS the first thing I try to find out is does this fight need super high healing or is it more DPS and a bit of healing or full out dps.
Then I find the best gear and perks for it and try to contribute as much damage as I can without dying and without anyone else dying due to lack of heals.
Now the top tier fights are pretty good at making player skill the determining factor for good dps rather than the class. Yes DPS DTs with VoM do insane dmg but they will also die fast unless played by a very good player.
