I do agree, they need to bring the trade system back.
I do believe that a lot of people stopped playing when the trade system was taken out.
There is no community involvement with no trade system. Obviously you will always get those kinds of people that was to scam people or get something for free.. but one bad apple does not mean the whole barrel should be dumped out and thrown away.
with the trade system, it gives people the chance to work for something. It could be from leveling sailors and selling them.. it could be supporting new players with points and credits.. it could be supporting the players that do not have a way or the money to spend in the store to get sailor items..
Either way, things like this always comes with a disclaimer. SDNet is not responsible for the poor decision making and actions taken by the individual. Scamming will be handled correctly, and your crew and or credits will not be replaced.
or something like that could help. Either way, the trade system would bring back a lot of help, and player involvement.
