As for the debate on weapons, it was said that we could only swap out what is in the first tab; that is 20 spaces. If you want potions, multiple weapons (main and minor), shields, bows, quivers, arrows, etc that space will fill up fast. Personally, although my characters often have a backup weapon, I rarely use it. My ranger probably switches weapons most, from bow to two-weapon fighting gear. Except for Paladins, I don't carry a shield.
Knowing how they are constructed and worn (SCA events, etc), these are not easy to get off. I could see someone carrying a buckler and a bow, and great weapon, but two shields is unlikely due to their encumbrance, which is not just weight but size and "bulkiness". The same goes for 2-handed weapons. If that is someone's playstyle, however, and they want to try their skill under these guidelines, the I am okay with it.
