You can't really judge the success or popularity of an MMO on a single, minor forum.
As Stratics doesn't have a Pirates of the Caribbean Online portal, there is little to attract a community of players.
There are busier forums, dedicated to PotCO, however.
Ultimately, though, every game has its problems.
Just as every person enjoys different things from games.
If a player enjoys PotCO, then they should bother playing it.
