Executive officer -> i agree with you
Executive recruiter & recruiters -> pretty much we all vote on apps and especially lately we haven't followed a real order to test people: leader, co leaders, council members and members too were testing, so i think it's better to keep the testing thing between the higher ranks (from council members to leader). If in the future we recruit a lot of people and we need more ranks we could reintroduce recruiters, but at the moment i feel that they are pretty much useless.
Veterans -> never really understood this rank, it doesn't gain any privilege, we don't really need it.
Trial members -> this rank is useful only if we use it, i noticed that all the unranked players were considered to be trials, but weren't moved up to Trial rank. So if we keep it we have to use it too, or it will remain ever empty.
