I thought the stream trading aspect was one of the few things keeping this game alive.
Never in a thousand years would I think they would do this.
I consider myself a veteran of this game, and knowing my loyalty to the game will end in nothingness after it officially ends is disheartening, as I won't be able to trade it off to another game.
This is absolutely the final nail in the coffin. SK steam trading was one of the only real lifeline this game had to attract the 2011-2013 crowd of SK players that make up 99% of its player-base. This decision to remove one of the sole things keeping this game due to the few people who take advantage of that system is like tearing down a dam because it had a few leaks.
I feel for every single merchant in this game who has invested in other markets outside of SK as well as SK itself. You were forgotten. The scammers won. RIP Spiral Knights 2011-2019.
