So I've read through the OP and there's a bunch of stuff I disagree with.
For starters, I disagree with banning high tier obscure verses. Understandably, verses that are essentially fanfics should not be allowed but what about stuff like random mangas or games like Pillars of Eternity. Continuing with the PoE example, I made one profile of it a while back hoping to find a supporter. Months have passed and no one has turned up thus it would be considered obscure even though its a very famous Obsidian RPG IP outside of the wiki. In such a case, obviously the one who created the page ends up as the only "knowledgeable" and in case of CRTs, will end up the only one defending the stats they've placed. On the one hand I can see why the staff would suspect the person of inflating the stats, but on the other it would be extremely irritating that the key decisions to be made during the CRT are at the hands of people who know nothing of the character/verse. Even so, the CRT largely works and stuff, including calcs and statements can indeed be verified so I don't see what's exactly wrong with the status quo. I guess this paragraph is my take on the numbers of pages, stat inflation and CRT system.
About people being crazy over hax, well maybe. But is that really a problem?
As for calc abuse, regular members' opinion doesn't matter anyway. At best you can pass a rule preventing verse supporting calc members from evaluating calcs of their supported verses, if such a rule doesn't already exist. That being said, I can understand if ensuring this proves difficult as not every member is listed on the supporters/opponents section of a verse page.
As for overstaffing, I don't really see a problem. More staff = more likelihood of at least one being present during every minute of the day, to respond to emergencies like troll attacks or take part in the large number of CRTs you've mentioned. The largish number of staff also ensures an even distribution of power while also increasing the range of verses that the staff as a body has knowledge/expertise of. Besides, the inactivity clause exists in the Staff contract to cull the unworthy.
As for the new tier system, no comment cuz my participation doesn't usually go to such high tiers. Same for the Staff vs Community. If a problem exists, I haven't faced it. Although I did see Matt on one occasion drop into a CRT only to post a cynical disagreement comment only to not comment any further when people ask why.
Off topic but where tf did Star Wars get 155k pages from?
