18 str requirement for arbalest and free respec to errybody!
Imho great damage should be followed by great strength
So you probably think that a handgun has 20 kilos?
I wouldnt mind if xbows require something additional for use. Add a wpf minimum for each xbow would probably be the easiest part and you wouldnt have to worry that xbows get a bonus from it.
If you add PD there would have to be some kind of benefit for it. 14% damage increase per point would be wonderfull, I'd run around with 2 light xbows, 2 stacks of bolts and all wpf in xbow. If you dont want that, in order to make it somehow "realistic" PD could determine how fast you can reload the xbow, but that would result in very fast arbalests.
I'm not sure you would want that either. After all, you would have to post new QQ topics.
