Yes, I can definitely do more damage with the 4/5 t10 bonus :P I'm thinking 17-18k would be doable for sure.
I'd love to meet Akama, and ask him some questions, and his 19kdps on DBS seems very doable, but I'm not sure 26k would be achievable without any bug-usage. As you have seen my Armory, you can also see that I'm missing a good cloak :) I'm hoping to get Bis, or atleast have all non heroic BiS items, and then see what can be done. 26k seems simply mind blowing! Considering that rava's BiS list for 3.3.5 sims out to an average of 12.3 kdps, I feel that even with the perfect raid comp, 26k is near impossible. Even though, yes, WF/WF is positively bugged, this would not create such a drastic dps boost.
Also, that second, non-ingame recount seems a little dodgy, people won't refrain from PS.
What's your enh's name dark deeds? Btw, the PP trink is not very far up on our rawr, as we shouldn't be using fast weapons. Try to aim for the Halion 25 sharpened scale, WFShc, or even the Totgc Death's choice HC.
