I had a look at
www.warcraftlogs.com & guess which spec is number 1 for DPS in Uldir
That's right a ww monk.
In fact 2 ww monks are top 2 in DPS all stars

I copied the Talent tree of the monk named Rammonk in Zul'jen & it is performing heaps good now.
Even in PVP.
Maybe monks are skipping the monk mount series in legion and are skipping the chance to get Ban Lu.
Ban Lu is a very noticeable mount now..it is brightly colored & perhaps the best class mount in WOW
I do not see many Ban Lu's around as was in legion.. So maybe monks have become unnoticeable.
