Right, this has been bothering me for quite a while. I'm an accuracy trait captain, and I have some lovely [acc]x2 [dmg]x2 Advanced Fleet beam weapons. Well, they would be lovely... if every time I used Beam: Overload in PVP, it didn't miss.
I exaggerate slightly, but it really does feel as though whenever BO is used, my accuracy disappears. In PVE, this isn't an issue, but I've seen my beams go wide when targeting a huge-arse cruiser in PVP. Could the B:FaW bug be affecting BO?
