I agree concerning the shotguns.  I don't have too much time with Alicia, but I play Lycus a lot.  I feel that the damage falloff is just a bit too extreme, making the shotgun only really useful in melee range, which at that point your likely to already be swinging.   

I've really been enjoying everything else, but I feel the shotguns just don't feel very useful in most situations, as the game has a strong melee focus.  This also makes missions where you need to destroy things, particularly "In Shock" very difficult, making the character feel less useful.
