Brutus has more responsibilities to manage than I, but Brutus has a team of several developers putting tons of their own hours to maintain various areas of the client and so he can freely delegate several responsibilities to said individuals. He is still ultimately the final voice on large scale development decisions.
Likewise, instead of magically hoping that splitting the role will lead to more activity, you could, you know, actually help out now. Since that doesn't happen and instead I need to deal with random dudes promising to do N+1 of what I do, I need to actively maintain more things than other councillors do. I'd like to throw the power grasping accusation right back at you. It just seems like you want to split the role because you have zero credibility or experience in any PC duties and are hoping to split the position up so it wouldn't count against you.
People seem to forget PC is what it currently is because I built the position, quite literally, from the ground up. When I got the spot in 2018 the total of tools I had available to me were a google calendar that only like 2 TDs actually used. Couldn't
change ladder on my own. Had no actual funds available to me. Nothing related to a system for matchmaker. Zero information about TrueSkill beyond what I could figure out myself. Zero insight into tournaments. No way to contact trainers, gauge them, or work with them. Nothing about who to contact for what or what was currently going on in the client. The reason this position has the breadth it currently has is because I made it have it. I made it have it because I can do the work, the work benefits FAF, and the best path forward is for it to be under my active management.
You can't handle what I currently do? Great. Find somebody to delegate the respective responsibilities to or find the time in your own schedule to do all of it or explain that you will be downscaling what I currently do. Doesn't require a new council seat, same as we don't need a java server councillor, java client councillor, and python server councillor.
