Right now I have 2 players who are both using 2 PCs. The only time there has been any lending or borrowing of weapons was when a bludgeoning weapon was passed up to a fighter in the front of the group to deal with some skeletons in a narrow hallway. Otherwise there is little or no sharing other than what is common when everyone has only 1 PC. But then I have always had a group that divided wealth based on what was best for the group rather than everyone trying to get their share. Roleplaying is working out just fine as well as the 2 PCs trade off the spotlight. And neither of my players would ever "kill off" a PC to get to make a new one. If they were unhappy with a PC we would work something out to replace it. I dont go for the "play that one until its dead" mindset, but then I have never had an abuse of it.
