Elite is accessable and most are still checking things out. I have only begun to look at the "Improve" topic which offers suggestions which may or may not fit your style of play. Additionally, after having looked at most Primary weapons, the Secondary weapons seemed to give their advice in German even though Elite knows my residence (America) and indicate the American flag as my Country.
I have not used any other feature as of yet.
