Also trading tomes and healing, wouldnt be good, now when you take a tome, your teammate should get a bandage instead of a healing potion. Adds some difficulty to taking tomes imo
Yes in quick play the potion swapping could be a nice QoL, especially since not everyone is using loadout mod, so there isnt really a way to check what trait yhey are using, but when playing with friends or a friend, it gets pretty easy to know what career makes the best use of a certain potion.
Sorry mate, I´m not really seeing how adding this feature would take something away. You´d still require coordination with your team mates, I´d say you can coordinate even more since you no longer have to rely so much on which item drops when and who gets there first. And unlike the current system, it allows you to adapt your loadout to the current situation. Maybe one of your players was downed while a potion that benefitted him dropped (or he joined the game later) so someone else took it. Maybe the player who originally carried the valuable item is now low HP so you´re giving it to someone else, etc.
The current system is also pretty counter-intuitive, from a logical sense. The fact that, yes, you can trade items, but ONLY if a third, unclaimed item of the same slot is involved, is a pretty weird state if you think about it. I cant think of any example where things ever worked that way, where you need a third placeholder to trade three things.
