The main problem is the ARR baits. The other expansions would only have a half dozen or so baits to worry about. ARR has around 30 I think. Consolidate those baits so there are only about 8-10 needed and it would free up a fair amount of inventory space.
Players can also learn to not hoard leftover bait and lures. Do you really need those Pill Bugs and Lugworms anymore? They're cheap for the most part and the non-scrip items are usually available on a vendor in the zone where the fish can be caught. I mainly keep the scrip baits since those are the ones I use most frequently anyways. If I need a different bait for something, I buy it off a vendor when I'm heading to the fishing hole then vendor/discard the leftovers when I'm done.
