I joined Congress in '08 when Tink was handing off to Rudo, so I will personally lament the loss of this faction - and while I went dark and stopped playing Disco almost a year ago, someone needs to say what I am about to.
I think that, when all of the individual issues and complaints are summed up and looked at in the long view, that the dynamic is very easy to read.
Congress was populated mostly (not all, but mostly) by mature players - by that I mean parents and adults of advanced age.
It was also, accordingly, populated mostly by people with little to no interest in pew, whatsoever.
It was in all seriousness always a trading faction, whether legal or illegal didn't matter.
But it was a trading faction made of people who were very practiced at avoiding pew - for the most part.
And I think this is what pissed off the 'kids' so much, Congress' actions and RP were designed and cultivated strictly to leave pew-whores frustrated - and it worked.
Lots of players who liked the occasional furrball joined, and when they found out Congress didn't want a fight every day, or at all really, they left for other more action-packed factions.
I saw it all the time.
And to those who say Congress 'harmed the server', pay more attention.
Who did a faction call if they wanted 15 ships to deliver enough base materials to build or upgrade inside of 8 hours?
Congress, that's who.
Secondly, multiple Congressmen have become admins over the years - not something handed out to abrasive or harmful players.
Thirdly, I myself wrote over 300 RP posts under my TFinnegan account, and I was a slacker compared to some in the faction.
And in the end, as RP goes the way of the Dodo, and more and more quality mature RPers leave to be replaced by pew-happy children, the server gets what it deserves, Huggie standing over it waiting for it to burn.
Matches in hand.
