I'll use values from 60 as that is what I'm most familiar with.
10 vers = 8.5 crit = 8 haste = 1%
But as it was mentioned, crits only deal 150% damage in PvP, so crit's value can be halved in regards to it's efficiency for raw DPS output. Crit is also affected by mathematically derivative diminishing returns.
However, in PvP, burst windows, time between fights and engaging players on less than full health all affect how each stat should be weighted.
What I recommend is aiming for dealing a certain amount of damage that would be required to K0 someone. Then you will need to playtest to see if that burst window is available often enough and if whether or not it is effective. If it is not effective, more Vers/AtkPwr and Crit will increase your efficiency more than more Haste. If it is effective, you can begin shuffling resources to allow you to do it more often.
Fury has access to Crusader Swapping at lower levels and Destiny/UTB stack at higher levels, so having enough raw power to pull off quick kills is reliant on those procs. Since hitting hard (via procs) and how often your burst windows are available are both determined by haste in this regard, Haste should be your #1 priority.
