I'm not sure he's talking about actual rules change. In NWN1 this was handled via the "dance of death" and NWN2 you just sort of stood there, but both had miss animations
BG1/2 I was so focused on the entire party I never even noticed if any particular attack hit or missed.
anyway, "handle it" doesn't necessarily mean rule change, or it could be such a non-op change (e.g. every attack does at least 1 damage or something like that)
EDIT: Oh, but I support the premise of making things optional, but not just rule alterations, make everything OPTIONAL (i.e. give us a toolset :))
