So why bother with alternate weapons?

So although the difference is nice to know, so many of the higher level skills have their own hitboxes (Brandish, Brave Slash, Blast, Heaven's Hammer, Charge Blow, ACB)

Are they changing Charge Blow/ACB? Currently the first target needs to be in normal hit range, the 200px range applies in distance from that 1st mob when picking additional targets.

And are 1h BWs SwordOS? I've always found their swing range atrocious.
