The subject pretty says it all.  I'm admittedly not particularly knowledgeable about weapon and armor proficiencies in BoL versions and BoL derived games other than knowing that H+I has armor proficiences but I'm not sure if any others do.  Is H+I the "crunchiest" BoL game and do you feel it's ok there as presented?  What about adding it to BoL Mythic?   Obviously it's subjective but I figured I'd ask as BoL is a pretty tight and trim ruleset so there may be strong feelings about complicating it somewhat with the addition of broad categories of weapon and armor gained with certain careers as the standing for classes.  Thoughts?
