shortbow?
Running both bows is pretty uncommon and generally not adviced because you then don’t have a defensive / mobilty weapon set (such as S/D or GS) which most people want. Also since the 2 bows are bent towards different builds (LB being power and SB being condition / hybrid) it’s pretty hard to make a build which can justify using both.
In regards to the SB itself… A lot of people don’t like it much or consider it to be of much use, although personally I still feel it’s one of the best choices for any condition or hybrid build which has precision (so Rabid, Celestial, Rampagers. Not Dire / Settler / Carrion) because of all the bleed procs. It can do serious damage in such a build and gives you a solid ranged / kiting option, which other condition / hybrid weapons like Axe or Sword don’t.
