I don't think there's anything wrong with putting an initial analysis for a new mon with just one common set. We can always add the rest later with additional set analyses and to be honest I think it's really important that we have at least something other than sample sets for new mons, especially important ones like Aggron. For reference, Omastar and Charizard dropped in February and Omastar's analysis didn't get completed until a few days before Gastrodon dropped (which is a big threat to all sets); mostly because there were lots of viable sets. This meant that new players didn't have reasoning behind popular sets until months after it dropped, and almost immediately that analysis became somewhat outdated. Charizard still hasn't been written up, mostly because of different people taking it over at various points but also partly because there were like 5 sets being considered at one point.
I think a good structure going forward would be to upload the sample sets, then upload a version of the analysis with only the main set being thoroughly analysed and the others being sample sets below, then the remaining sets being written up once the overview, checks and counters, etc are already on-site. This also gives us the flexibility of being able to have different people write up the different sets who know more about how they work.
Let me know what your thoughts are on this. I also agree that CB Aggron should be the main set for now.
That makes quite a bit of sense to me. I'll work on writing something up tonight/tomorrow morning and get a thread set up. Aggron certainly has a lot of usable sets but IMO it quickly goes from best set to "you're only running this because YOU like it" real quickly.
Concerning any of the other sets, I don't think RP is good enough because it's like a Rhydon with less opportunities to set up, worse STAB coverage, but better raw power (Rhydon also has SD too so this last point is somewhat moot). I've tested with SubRise and it's only good enough for OO. The only sets that are worth writing up are CB and Lead.
That's exactly what I was thinking. A boosting Aggronn feels like a wasted team slot. It's not terrible but inefficient. CB and Lead are my two front runners.
