It's been historically accurate since the rage issue was fixed 10 months ago or so for long duration fights. It's been historically inaccurate for short length fights. Granted we're all aware of the limitations as we know it isn't set up for those short length fights. But when i can beat the spreadsheet and i often do. Example Festergut
WoL report 13,151 dps vs spreadsheet's 12,022 This is when i look for ways to make it more accurate for these short duration fights.
Shattering throw you can just replace the 3 instances of 300 with G44 in cell D73. Then remove cell AP37 note that says /5min. Not sure if that's the correct way to do it.
Tricks i'd probably leave alone as you can set how many tricks per 30 seconds.
Hysteria has a bit longer of a time table with how many per 3 minutes. Changing that one would require changing cells D78,D79,F78,F79.
Then you'd also need to change Death Wish in D79 and F79 to work with a duration.
Recklessness would also need to be changed. Although i don't see it referenced anywhere. Maybe i'm blind.
It seems like a lot of work. I was looking for a baby step in the right direction with the Bloodlust/Heroism change and not a complete overhaul. Especially as we move closer to Cat and Haste becomes one of our primary stats to use.
