One more thing - if the price of xbows will be same in Strategus, I doubt if you see Siege Xbow on many sieges...
In other words, if the upkeep reasonable limit is 25k, that means you can wear rags (Pilgim Disgiuse in my case), best xbow that does not kill (remember loading time), low tier 1H + low tier shield (siege xbow + steel bolts costs 20k!!!). Xbower does not seem to be a viable option anymore... Eh...
Guys, to make it clear, I am not trying to compare xbows vs bows, they are used in different way, xbower usually (or used to) have sensible secondary weapon+1h, archers often have 1h or 2h "just in case" with little WPF. Builts are different. I am just noting the differences after 0.210...
EDIT:
I just learned that regular xbow + regular bolts need 6 shots to kill guy in Heavy Strange Armour + Wisby Gauntlets with 0 WPF IF.
