Wait, how can you turn down a ranking? 'Cos it's imposed by the Ranking Office.... and whether we want it or not, everyone gets it. It's like how all Regulars and Rankers are graded according to their abilities, remember?

I suspect the only reason one can be excluded from being ranked, is if it's someone like the 4 children of Masceth. That's 'cos the Ranking Office seems to have some kind of relation with the Gong Bang(which is above the Tower politics) and they wanna try not to be too biased.

If not, otherwise, there is no good reason why someone is "special" enough to get to be excluded from a Rank, or from moving up in Ranks.
