To be honest, I am conflicted with the idea of removing or not removing.
On one hand if removal, it would honestly give a reason to fear the unknown if it lead to everyone being involved with the Map game. It would be incredibly interesting and perhaps a way to introduce factions not generally seeing the light of day. Permanent hexes that more or less start to fall apart when the other faction starts going inactive or just stops caring, making it an interesting piranha effect.
On the other hand, it would remove something rather unique for the website. Some love the build up and use it for major story telling...Brotherhood of the Maw and Galactic Alliance is a good one to point at in recent times. Some Major Factions exist primarily to tell their story...how often can you say anyone sees the blob of the Bryn'adul or the Empire ramming through areas at top speed, it just not happen often and the visual of it is striking.
Personally though...I hate Major Factions.
As one used to say, the tired trope of the same people popping up and doing Sith Order 2: Electric Boogaloo is...well tiring. One can only do so many reruns till finally people just steer away or just do not wish to interact with the other. Other times the Major Faction in question has progressed so much, it is difficult to write with others without getting talked down on or being ignored when asking questions, even as simple as "I wish to do X in the thread, can we work it or should I not?" then after doing it while waiting a day, get bashed for it. Did I also mention the social groups that some form, some that is just difficult to even talk to them if not with "The Klick". (Those who got the reference, I love you)
More likely though, I am grumpy man who just does not want to deal with the bull*@&# anymore. If you're a Major Faction, I am sorry but the chances are I hate how it is, the people in it or how it runs. I will pop into a random dominion from time to time when a moment strikes me early on or I can see a bit of unique fun to add into a story. Otherwise though, I steer clear of things like the plague...
Also anyone who has had friendships get ruined through roleplay, I would not have called them a friend in the first place and just move on with your life. People are assholes and sometimes it takes a while to find the worst of them.
If the blue man himself, if he removes it today, I don't think I will shed a tear...but I know a lot of others would.
Now excuse me as I run from the angry mob I most likely made.
