I used to be a commissioner and staff, in two different servers. I really would want you to be in staff but honestly, depending on the quota and how busy the server gets with tickets, trying to be active on both commissioner and staff can be very draining, it stops you from doing one thing and then it's all about your persistence and will to take on two things with high expectations on activity, leadership and care. Your RolePlay does get mostly taken away from you (yet, still depends on the tickets) and while you should already know this and have experience.
From my own experiences being both roles at once,
I wanna see you be commissioner for longer and I wanna see you settle more and relax into it before taking on a staff role if I'm being honest. However that's not going to stop me from giving a +1.
Sorry if settling and relaxing is a hypocritical statement from me, I just don't have any other primary sources of knowledge of you other than being a fresh commissioner from 2IC.
The responsibility is there, the maturity is there, you are fit for the role knowledge wise.
I'm only left with questions here wether you're able to hold onto these roles for a long time.
Yet, I do trust you to be able to obtain these roles. I'd like to be supportive about this.
