From MainTankadin comes this little gem - a WWS parsing tool that will output threat per second based on the logs.
This isn't useful for e-peenery. I'll say that right now, in case anyone cares. What it is useful for is gauging how actual changes in gear affect your threat from week to week and what the actual source of threat is in fights, especially as your role changes.
For example: this is the WWS of a recent Morogrim fight that I tanked. And from that report, I apparently did 803 TPS. That's not so bad; that means melee can put out 900 or so TPS, and ranged can do 1050 TPS without going over - and of course, they're salved and have other threat reduction caps. From this parse you can see that Maul is a huge part of the threat, more than any other single source. In this fight it is 37% of all threat generated.
What's more interesting is to see the miss numbers. 30% of all mauls were missed! That's a huge chunk of potential threat, right there. I believe for Morogrim I was wearing my max avoidance gear, so that explains that.
This should demonstrate how good the brooch of deftness and other hit/expertise items really can be. For instance, just from maul, if I were using the brooch of deftness I would have reduced that miss percentage from 30% to 25%, roughly. And just from mauls, that would have increased my threat by 2.6%. Just from mauls.
It should also tell you how huge maul is for threat generation. Morogrim is an interesting fight in that you want to max avoidance and you will also often be rage-starved, because he will get big strings of misses or just choose to not swing for a while. Survivability is the big key for Morogrim, not threat. For a threat race you can look at something like Void Reaver. VR also wants as much avoidance as you can muster (so you can avoid the knockbacks) but also as much threat as you can muster (so you can hold onto him after them). In this fight I went for more of a threat-centric build, and it showed - my mauls missed much less (18%) and my threat was at 923 TPS. In that fight, maul actually made up even more of my overall threat - simply because I used fewer normal swings.
Up until recently I hadn't quite realized how large a threat value maul really is. This should show both the value of damage to your threat and the value of hit. It also shows how badly threat scales for bears; Maul only adds 176 damage per hit, no matter what, so as you increase in gear the relative threat that this produces becomes lower and lower.
