I envy ninjas that they invest their skill point and wpf to throwing while they could invest 70-100 wpf to xbow and with theirs agi build (21+) could still swing katanas at speed of light. And be much more dangerous than with any throwing weapon. Try to hit something with 70-100 wpf in throwing
About good players: We have very good players on EU. Dave_ukr is example of very good player which will be able easily to top scoreboard as infantry still he uses arbalest in which he is even better. But one Dave is enough and he is bad example for newbies to start their path to darkness.
Not to mention our Darth Vader and master delayer sir Agor which is consumed by darkness completely
About reloading speed: yes 2slotet xbows reload relatively slow but xbowers are almost never seen in open.
Their tactic is to shoot and scoot or to be corner spiders sitting in their nests or crawling slowly along walls.
I've seen pure xbow build with hunting or light xbow reloading and shooting faster than my 140wpf unloomed tatar bow archer
So in one going pure Xbow is not sign of bad player but complete retardation and twisted nature
