Both apps for MRP have told you that you lack being known, and that's just in general.
When it comes to community, you should branch out from just 2GA. It's weird how people still expect players to main both sides and know everyone but it's definitely important to get some interaction with other RU factions and to participate in their tryouts (even if you fail). Anything to get people to notice you is going to be extremely beneficial when applying for staff, because most likely people will just leave a kind +1. Also forum activity helps out a lot. Build yourself a description and comment on applications, suggestions and other forum things. It's a good way to get people to notice you on the forums too which is even more support.
