My martial characters tend to cycle between numerous weapons, but the system tends to work against it. It usually only really make sense when encounters are designed to frequently require cycling between melee, ranged, and throwable melee weapons.I have to wonder, though, how many fighters change weapons like that anyway? It's been my experience that they only change if they get a better version of the weapon they already us (if then). Most people seem to stick to one or two weapons. Especially in 5e, when so few creatures have any sort of vulnerability or resistance to a particular type of weapon, and there are fairly few weapon traits anyway.
It also helps if you're the only real weapons guy in the group such that multiple cool magic weapons land in your inventory.
