Please SSG, no more nerfs. Thank you!
This "test" does not work. Imbues still aren't effected by -threat and it's not pure total damage to steal; if a single hit is "big enough" you can flip something even if you're the lowest total damage dealer. I suspect other factors, too, but they're hard and tedious to test; eg. low defenses, distance, level, lack of movement, etc..
As an example, I have a couple ranged. One is a grade-A thrower that auto-attacks around 10~12k per hit. One is a repurposed HC 1st life INQ with autos in the 2~3K'ish range. Both have -80 ranged threat. The INQ will rip it right off a tank and it's doing about HALF the total auto-attack damage of the thrower. The Big-D thrower is about 5~10% imbue. The INQ is about 80~90% imbue.
As another test/comparison between the two (cuz I was curious), my thrower can solo kill Zulkis (after Irk) before the raid finishes killing either Rudus or Gish. My INQ trying the same trick can't kill Zulkis before the raid finishes both Rudus and Gish and turns to Zulkis.
Basically, just ignore agro-rips. They're nearly meaningless unless you have Defense enabled. The +threat from that is enough to rip it from almost anyone even with ultra-low damage.
Then... we really need a parser. Not only for just DPS but for heals done to others, total damage taken (not just absorbed) and even # of CC'ed mobs or seconds CC'ed. Most buffs? etc.
After reading this thread, I think most DDOers are old enough and mature enough where they would take this tool to further improve and polish their groups/raids.
I think for most established raid groups it'll be more ,"oh I see you're a dedicated TWF DPS.. but you're consistently off by 200.67 DPS compared to the other TWF... let's chat with the other TWF and find out what's going on and fix things."
It'll be a net improvement for a lot of players in the game.
