Whatever happened to good old style D&D traps?  Pit traps, drop down wall/door traps, flooding a room with something trap, trip wire traps that cause an avalanche, floor traps that cause lasers/flamers to shoot out of the wall or electrofy the ground, etc etc.  I'm sure using a shield and walking down a narrow corridor gives you very little visibility to what is in front of you.  Even just flanking the person would cause some grief.  IMO, i believe large shields should give a -1 Agility Bonus modifier.  I've used riot shields, and it's not easy running with them (damn near impossible actually while using them correctly) and dodging is just to much work.  Can't tuck and roll with a shield on your arm, I'm sorry to say.  A buckler or medium round shield, yes.  A full body riot shield……. yea, not so much.

Anyhoot, wasn't this topic about shotguns and how absurdly powerful the BoJ one is?

It is pretty redonkulous. I think the broad message is that not everything in every rulebook is balanced relative to everything else, and the GM will have to make judgement calls about what he allows in his game. Never assume that 'if its in a book, I have to allow it.'
