This game was doomed and a lot of old testers saw it coming a long ago.
Simply put, the "hardcore" (alias the crapton of hours needed to make just everything) game mechanics (that were set up with the purpose of monetizing hard with DLCs) are not able to keep people engaged, because of the lack of variety of content.
The creation of big zerg nations was the direct consequence of too much effort to be put in setting up port bonuses and the high cost of shipyards and other structures plus the choice of devs to wipe at launch.
After getting their fingers burned by the wipe at launch, a lot of players (mostly the not "only PVP" and the "no 24/7" players) did not want to risk loosing once more the results of their awful (re)grind process and then joined the zerg.
If you do not wipe, game will maybe survive as it is for some month. If you wipe again, game dies the day after.
Greg, live with it. It may be sad … but that's it.
