I understand some of the concerns, the reason why I'm not too worried is because right now with the server populations as it is, and how it is not summer, it is not easy to get the amount of vouches, especially from a D+ as they have their own lives, and can not get on servers to be that 1 extra vouch for that person who might need it. I think it's fine as our process to get mod is significantly harder than it was a few years ago, and is heavily discussed between many staff behind the scenes on top of getting community feedback.
On top of this, we want people who are active on the servers to be members so they can help us improve, the harder it is for them to obtain membership, the less likely they will stay in a place they feel "unwanted" if you will. Members who do not represent the community well can easily be removed as well. We do promise to not sell staff anymore so we do have the advantage of good quality staff at all times in our servers compared to other more populated but pay to staff servers.
If we want to compete and constantly improve, we unfortunately need more eyes on our servers and we believed that this would be a good start. Please feel free to continue giving feedback as discussion is important with issues like this.
