Helpers are trial staff members. The helper role is to see how they would act with the most basic of commands. Giving mods too much power, and if the mods don't know what they are doing. It can end up causing too many issues. There are reasons servers don't give helpers any ban perms.
I see your point with admins/mods not being active, but also keep in mind that all this for us, is voluntary and some of us do have important things to do. We are active as much as we can be and always have discord as a way you can reach us whilst we are offline.
