Well I am hoping horoks gets a good look at with this balancing. In the Hands of a Bst its a great item, in the hands of a Mnk a alright item. There is a bit of difference between the weapon in the two different classes, and honestly, its because the two classes have too much difference between them. Monks have different needs from weapons than Bsts. My own parses show that Horoks current setup is as strong a bare-fist (1k base Str/dex + Buffs). Without a good secondary though the idea of swapping it in for DPS is meh. It is however a useful stat stick while still retaining some DPS. Personally, I'd just prefer a less DPS sustain item for auxing, Rampage, WW, off-Tanking. Bsts of course would very much NOT prefer such a change, and because of this, I kinda think Horoks should have two different versions. A Bst and a Mnk version. Monks when using a weapon kinda think along the terms of Tankage with a little DPS; while bsts think of a long delay and decent proc-or proc rate- for mimicing. If you were to do this, I personally have a suggestion or two for the mnk version. I leave the Bst side to the bst.
Suggestion#1: A decent lifetap/Leech proc.
A lifetap proc can be useful without doing DPS. I think in terms of what a Mnk would equip a weapon for, it would do decent, and it would be a DPS decrease. Leeches are pretty good, but not great DPS/Sustain due to Reprocs. Honestly, I'd settle for old Horoks procs. Its not like the Over-writing Regen matters to mnks anymore, and the proc has a decent amount of Sustain/dmg. Though having rarely used the old horoks I can't say if its too strong or too weak.
Suggestion#2: A Beneficial Proc
So, right off the git-go you kinda have a really big area for this 1, but there are a few areas I can think of that would work with Monks. Runes similar to Enthann's Guard provide a Proc and something to help with Whirlwind, Rampage, Auxing, and off-tanking. If it has a decent proc-rate and timer (maybe 2 mins or so?) you could even benefit from it while Bare-fist, assuming it stacks with Rbow of course.
Next up, A self-heal or HoT. These are similar to lifetap/leech procs cept, no DPS on them. You can compensate for that with slightly stronger healing. This imho isn't that great of a solution, but something all the same. Over-haste, or even a Yaulp 4 proc can be useful, and this adds a sorta of swapping rhythm to mnks as they would be swapping the weapon in and out for them Yaulp procs. Sounds good in theory, don't think it would be that great in application.
Anyways, maybe someone else can think of something better for this section, which is the main reason I threw this in here. I'm sure people can come up with a decent idea here. Maybe even no proc, lots of Double-attack on the weapon, and a clicky.
Suggestion#3: Gloves
This one is a little weird, and would take a whole rework of the weapon. Something that I am assuming no one is up for, but would provide Mnks a in-between area for gloves. After all the gloves kinda go Silence (or UC gloves) ->BW Gloves its only a 4 tier jump.
And that is honestly all I got off the top of my head. I know this is centered around balancing loot, and a lot of my suggestions are rather sub-par, but my main goal isn't so much to push for these changes, as to get people thinking. Maybe someone comes up with a great, non-OP solution to the weapon and both Mnks and bsts get a benefit from the same weapon. Either way, I just want to point out that in the over-all idea of Mnks and Bsts sharing a weapon is a bit lopsided.
