well the thing of xuens vs the feather is that feather is a drop and xuens is a BoE.
its a very good BoE for its ilevel and if you can't GET the feather/spark to drop it will stand you in very good stead.
8k+ gold vs 1750 honor until I get feather to drop
I think I'll go with 1750 honor.
I'm quite confident I could earn 1750 honor faster than I could earn 8k gold. I'm much less confident that I could do ten runs of Forgotten Depths (roll + coin on Ji-Kun, 15% chance of loot, 3 items on loot table = two 5% chances per week, thus an average of ten weeks to get Feather) in less time /played than it would take to earn 8k gold.
But at that point, I'm inclined to think Brutal Talisman of the Shado-Pan Assault might outperform both - it procs slightly more often than Feather, and Feather's buff is weaker for most of its duration.
