no reason why you SHOULDNT be able to carry as many items as you like with the current slot system, the arbitrary 4 item limit is counter productive.
You're foolish if you think people are going to run around with a ton of extra 0 slot weapons...they have weight associated with them, not to mention they suck. I'd love archers to load up on 0 slot weapons, as it'll make them easier for me to catch.
You guys are paranoid
