I made STF HA char and played a bit yesterday at EU_4 and today at EU_1. My current HA KDR is Kills/Deaths: 73/39, 1.9:1.
My HX KDR is Kills/Deaths: 639/300, 2.1:1, so just slightly better (HX is reskilled, also level 30, so situation is equal for both).
HA accuracy is good enough to play well, even with this STF, level 30 char. My build is 18/21, 163 WPF in Archery, Yumi +3, Bodkins +3.
I'm using 3 packs of arrows, so I have 51 bodkins (pierce damage) in total. That's 2 times more ammo than HX has.
The damage of HA is really weak. I need to hit low armored enemy (like archers) 3 times to kill them. Killing harder targets is huge challenge, I need about 8 accurate arrows to kill heavily armored targets (I will try to do more damage tests today evening).
From my observations, it's much harder to go for enemy ranged as HA (comparing to HX), so I try to stay away from enemy ranged. I would need a bit more accuracy to go for enemy archers (18/24 build could be much better for that). Same time, going for enemy horsemans is fine, also disturbing enemy infantry is much easier because HA don't need to reload.
I'm still not used to Yumi arrow speed, which is really slow comparing to anything else (arrows drops very fast, I can't get used to that). I'm sure I will get better with some more experience.
Anyway, the class seems to be fine. It has less damage than HX, but 2 times more arrows (and i'm counting Bodkins here! It can be even more with different arrow types!). I can also shoot 3 times faster than HX do. I would love to see a bit more damage from HA, especially against low armored targets, but that would make HA far superior to HX due to more ammo and much faster shooting speed. But the class itself isn't that bad, especially I don't have any experience in HA yet, it should be better when I start playing it regularly.
I can't agree that HA is much worse than HX. It's definatelly harder class to play than HX, but it has it's advantages over it.
HA: Much faster shooting speed, much more ammo.
HX: Higher damage, a bit better accuracy (and ability to hold crossbow in ready to fire position).
If someone is interested, those are my builds (both useless in melee, both builded to be good in shooting):
Level: 30
Health Points: 53
Weapon Proficiency Points: 5
Strength: 18
Agility: 21
Archery: 163
Riding: 7
Horse Archery: 3
Power Draw: 6
Weapon Master: 7
Level: 30
Health Points: 44
Weapon Proficiency Points: 1
Strength: 9
Agility: 30
One Handed: 85 (as I found out it's useless with 0 PS)
Crossbow: 170
Riding: 9
Horse Archery: 5
Weapon Master: 9
(I think I would prefer 12/27 HX build now, but I don't want to reskill and lose experience again)
HA will be even better with high level (33+), while HX can't get more accuracy (accuracy increase from WPF is limited) nor damage.
