I agree, lately I've been seeing alot of people do this on freelot items not just for seals, but anything in general wether or not they intend too or can use it. It's not unreasonable to think people will start lotting everything after such an update is made.
Another big issue I see happening, is monopolization of NM's that are easily soloable. Using Siviards method, anyone that can solo a NM can just spam said NM until they get all the "junk" seals they want for anything they might need. Short term this would be just an annoyance, but what if everyone starts monopolizing a NM that drops a KI for another NM. After that point it starts to impede progress for anyone trying to do bigger NM's in Abyssea.
A more reasonable option would be to allow players to obtain seals by purchasing them with Dominion notes. I know many players have a stockpile of these notes and they are relatively easy to obtain, so adding a heafty pricetag for each seal would not be unreasonable.
However, I do see a use for Siviards idea. Instead of a seals exchange, the idea of exchanging trial items for others is a bit more reasonable. Let's be honest here, some of the trial items needed for certain Emp. weapons are extremely difficult to obtain Vs. others. At the same time, we occasionally obtain an item off of some of these monsters such as Oberons Lantern. Now suppose we could exchange these items with a 2 - 1 ratio.
The catch would be you could only exchange for the higher Tier NM items (Megaboss Teir and above) and exchange items for others of the same Tier. An example would be you could trade 2x Gavloid Shells for 1x Oberon's Lantern, but you can't exchange Gavloid Shells for Alfard's Fang, because they're on different Tiers.
I'm just throwing a random idea based off Siviards, but it allows all players to get their hands on Emp weapons at a reasonable pace. Since the trades could only be done for higher Tier NMs and for NMs of the same level Tier it prevents easy monopolization, because players have to build up to the NM and KI's are limited to one per person.
