I see a lot of people complaining about not being able to share drops from parties. A partial workaround for that when it comes to random sharing of loot would be for people to opt out of getting a dropped item.
In Tera for example you can choose to not roll for certain drops and let other people have a chance at it. I think that being able to opt out of certain loot would help support oriented characters who otherwise would have a hard time getting loot or themselves.
Although this isn’t a complete fix as there are a couple small instances where it could be a bummer.
A rather ambitious idea:
Another workaround to trading would be to enable it through the guild system. At the cost of some kind of contribution points you could trade with your guild members. This could be amplified by having Guild Wars losses directly impact the ability to trade but that’s up for debate. This system would seem highly inconvenient to bots.
