While having more than 1 super is not anything inherently wrong, I don't believe anybody but flame should currently be one.
We've seen time and time again that Sakura has been anything but receptive toward criticism, and as a matter of fact has consistently caused issues for years. He is not somebody I trust to "keep flame in check" especially when his current position makes it all the more difficult to keep him in check.
The only other mod I think is qualified/well suited to be a super is CowCow, and he only joined the team recently so promoting him at this point would just servento ruffle feathers.
Flame should be head mod, and Sakura should be demoted to the status of regular mod.
It was also raised in the Complaints thread that Flame should be a head mod and that Sakura should be demoted to a regular mod, but we little to know follow-up on that, though I suppose that's because the Complaints thread was for addressing broader issues, and this a chance to have a more specific focus regarding the team.
Go off with Cow, he's not the only one who recently joined. While Dad and Black have both been on the team before, their respective "returns" to the team are fairly recent. I don't think any of the current mods have been around long enough for a continuous length of time, nor would they be trusted with the position of being a second mod. So you're right to say that no one but Flame should be a Super.
Which is really our problem. We shouldn't have just one Super (The arguments in favor of more Supers do make the most sense to me personally), but we don't have enough people who actually deserve that position.
By the way, I'm also okay with abolishing the idea of section-specific mods. It's an archaic system that may have mattered back in the day, but I think the various sections have changed for one reason or another over the years that we don't need a "dedicated" mod. It's also seemed to be rather restrictive as a means for promoting people to mods, since the logic has seemed to be "This section needs a mod, so you will become the mod for this particular section." I like how the latest election was designed, not looking for mods of any sections in particular, but rather electing mods to round out gaps, and then assigning sections after the fact. I'm assuming this thread is started in part because now is the time when Black and Cow would be assigned sections, and the mods were discussing whether or not that much is even necessary.
But seriously, as Giga said, demote Sakura to a regular mod and let Flame be our sole Super. While I would prefer 2-3 Supers overall, I don't believe we're ready for that yet, and having Flame as our sole Super would be good in the intervening time until the team is ready for any additional Supers to balance out Flame. So Flame would unofficially be our interim Head Mod.
