I play a crossbow men / secondary 1h shielder
imho good support build:
Crossbow (regular, would love it mwed but will never happen, fast enough to shoot and reload normaly, hs for kill)
Steel bolts
Military cleaver (good dmg and range, slow but im low on wpf so slow anyway, sometimes use warhammer for fun)
Board shield (fits style, takes tons of dmg, enough to survive and fight again in better situation)
Kettle helmet, tunic over mail, mail gloves and footarmor (fits visual style, im a fan of that) medium armor, will save you more often then not
Skills:
15/21
max ath, wm, ps, if, shield
~70 wpf in 1h
~140 wpf in xbow
Then just play by shooting unsuspecting archers in the head, heavy armor dudes in the head etc. etc. when forced to melee, play defensively and aim to survive, relocate, shoot.
Takes a bit of 1h skill in general to be effective though, since xbow sux so half my kills are melee kills (despite my xbow focused build)
