Re: Making Hero 6E More Dangerous (Skyrealms of Jorune Conversion) ?
I really don't grok having weapon familiarities in a supers campaign. By tradition of long standing (and according to the rules, last I checked), anyone can use a mundane weapon unless the GM rules that your character has no way of figuring out how to work it, usually given in examples such as why your King-of-the-Jungle character doesn't intuitively understand the workings of the Great White Hunter's "bang-stick". The Mighty Arrow can probably pick up any bow and use it without WF unless his GM is a duck-head.
In a non-super campaign, I'd insist on weapon familiarity to avoid the penalty, but Joe Daggerthruster can pick up a shortbow and arrows and use them, only at -3 unfamiliarity penalty plus any other penalty a skilled archer would have to contend with. If he has combat skill levels with bows, I'd allow him to use those to offset his unfamiliarity with the shortbow, but I wouldn't let someone in a less-than-super campaign buy skill levels for weapons he doesn't possess in any case.
