Please don't just restrict it to melee weapons only, there are ranged weapons other than guns like javelins, shuriken and bows(if you can even hit in 1 range)...Also tome Ether Invitations are pretty fun to use and allow tank-breaking most of the time since it will target RES instead, and deal magic damage.

As for being on topic, I can agree on just disabling Ether invitation with guns specifically, as a good option.
