From a noobs perspective imo the biggest issue is all the large premade groups that take over servers and by doing that chase off most new players, which naturally causes the playerbase to decline. Those same people will generally blame everything else without realizing that they are the problem, similar things have happened in a lot of other games
I understand 100%.
We need to make clear to the newer players that it is completely acceptable to join those big kingdoms. We also need to make sure big kingdoms respectfully educate the newbies, given that they are active and they also give respect.
