I have fallen in love with the longbow/Shortbow combo, as I am mildly obsessed with archery in real life, and always saw a Ranger as a class that excels at ranged weapons.
Would this build be viable with that weapon combo, even though you mention sword/horn as your main weapon combo?
I'm using near equal build and I think you can try with Longbow/Shortbow combo, but shortbow uniqual bleeding effects will not be maximized without +condition damage traits. I really think that you should give a try to sword/horn as it is a lot of fun.
Personally I use longbow very often, it is a good weapon in connection with your bear for locations that you don't know and when you don't know what to expect. I'm switching for sword/horn+bird when I get to know what to expect from enemies or when playing with other people. I don't remember when I died last time. It is superb build and with s/h+bear you can kill 2/3 enemies with your lvl or even +1/+2 in few seconds since sword #1 skill hits multiple targets, so lvling is quite fast.
