I throw out rooms because even though it's pretty easy to get 4 of any room for a PC, your max number of rooms is 9, so there's almost no way to get one room type for an entire team. You can lock up to 5 rooms, and throwing out Revya's Home room (since it -can- be purchased), that still leaves three rooms that you have to scroll through on random over and over again to get a full set of 9 Los Banditos rooms, for example. And the random generator is loaded against getting multiple copies of the same rooms -and- against getting the better rooms w/ high numbers of formation squares. The chances of getting 9 of any room are something in the thousands to 1 ratio...
As for Revya getting squad summoning, I don't see why she would get to summon full squads of 9 units on Los Banditos when the PCs themselves aren't even getting room decors or support units... It would make more sense to hold her summoned units to DL-legal rules, too... So... 8 squads of a single unit on a null room would be pretty fair. Revya may have the unique ability to summon squads, but rooms and support generics aren't unique to her OR her summoned squads.
Assuming you -do- allow Revya to summon full squads of 9, due to the range of summoning, Revya can never get more than 60 units total out in one turn due to how summoning placement works. And I would compare their damage against other full squads instead of comparing it to the single-PC damage average. This would probably give you about 7x average damage all together, assuming you have them all on the (nearly impossible to get 9 of, in-game) Los Banditos room. Pretty awesome, but our highest Godlikes can survive it.
As for Fusing with townspeople, I actually already have the numbers for that in the stat topic, assuming that Revya has Fused with every NPC possible in the game. Aaaand... she -does- get signicantly stronger, but it's only about double where she was before, and the damage increase isn't actually very notable. She -does- become a lot more durable against magic, though. Still status-bait and very ID-able, though.
Adding in Initiative for her Demon Blast skill along with Full 60-unit Los Banditos Squad Summoning AND 100% NPC Fusion -does- make her pretty Bluelike, though. Zophar, Ghaleon, Souji, and Myria could probably play with her, but that's probably about it? Other high-durability types like PD, Jade, Fou-Lu might be possible.
Still, that's a lot of favorable calls to make. Getting 100% of the NPCs in Fusion is reasonably difficult on its own, but at least FAQ-able. 9x Los Banditos Rooms is ridiculous. Not holding summoned squads to the same criteria as the PCs is also pretty suspect. But even still, Revya could be beaten by the High Godlikes.
On the flip side, allowing -none- of that, Revya's still got fast OHKO potential, and makes Godlike. So it's not even a division change.
I understand the kneejerk against ranking someone with potential interp problems, but I think the problems are being exaggerated.
Ignoring Revya, though... if you'd like, I could go through the match bonuses in the stat topic and add a guideline for typing instead of relying on people remembering the class names. It's really not as much of an interp headache as you're indicating.
