I literally created a Facebook page which drew a lot of players to come, but a lot of quit due to these reasons:
The Login Bug Incorrect Password/ID - They think that the bug is actually really something wrong with their account and need to try again, but then give up after the 12th time they try to log on.
Lack of players online who actually help and give advice - From time online and standing in Suer to see both chats, u see new players go into shouts, asking questions and no one replies to them or even tries to help them. If I had no clue how to do things in this game and I asked for help with no response, I would quit too.
The leveling process - This is regarding to even Veteran players coming back and seeing this leveling process and they do not want to deal with it. I actually wanted to quit again when it took me forever to find a team to level my medic and was so boring and repetitive. I tried to get old friends to come back but they do not want to do the leveling to end game.
Broken Classes - Friends left due to their class getting so nerfed that it's unplayable and buff to classes that do not need it, but heard there are going to be changes, so I believe once these changes are made, the game can become active again.
I think a lot of people who are not veterans would not want to stay in regards of these reasons and even had some tell me these exact reasons.
I even tried to promote video content to the Facebook page, a lot of FK were happy to help and only one RG player was willing to help. I've spammed in the Vendetta discord and ingame for RG to submit videos so we can post them, but they just won't and I cannot force them. Even had MMOBytes try to promote SB as well. So, there are people taking a huge effort to try to promote the game. The staff are trying to make changes to the game and fix a lot of the issues above. If the player base actually wants the game to stay alive, they also have to make more of an effort to make new players feel important and accommodated.
