Like I said above, I'll go with the majority, but no I do not agree at all with removing 7-A. There's no several 7-A statements, there are several tier 7 statements. Unless we assume, for example, way bigger than baseline mountain size for mountain destruction statements, that's around 7-C or 7-B, plus other smaller calcs here and there. That is a big difference. If there were multiple, we wouldn't have such issue with revisions in the past.
I will never agree to Lancelot with Arondight comparable to Gawain. The only thing that kept Lancelot alive was the skill difference. I am not sure we would scale someone that could only stalemete and couldn't even put a dent on their adversary, to their level. He then destroys Gawain with barely any effort when he depowers despite Gawain and him being nearly equal even when Lancelot has Arondight. No anti-feat would ever support Berserk Lancelot not scaling to Saber Lancelot, you are literally told point blank that his noble phantasm catching trick against Gilgamesh would be impossible if he wasn't souped up with Mad Enhancement. Its obvious he's stronger all around, despite Saber suiting Lancelot better.
Scaling up NPs due to Durandina piercing Herc and Asterios both and one shotting Herc I am very okay with.
Same for multiplying 7 times from Caliburn for comparable or higher NP.
Never liked and never will the Photon Ray calc, especially as it is a grail boosted Servant. People were even saying scaling to Lord Camelot/Chaldeas would be enough, even though Mash did not block it alone...? I still lean for Likely or possibly due to Tesla. Tesla mentions his Full Power NP. There is lacking context, so it could either be full power lightning or full power actually calling the True Name, which is hax that would give no AP. Either or is just as likely. God do I hate vague statements, stop doing that stuff Nasu you little gremlin.
The Rhon stuff is hax, so nah. Layers are treated like literal layers of reality, not like destroying the surface by bombing it. Is a bit like Ea being the natural enemy of Reality Marbles, not because it has noice AP, but because it is an Anti World NP that can even erode the reality of the world itself, so its "super effective" against mini worlds, which is what RMs are. Or how Achilles NP shield would require an Anti World because it represents one, but even when we see it it really doesn't cover a wide area? Sure doesn't look as big as the entirety of greece to me.
I will never try to deal with anything Extra again as far as I can try. Decide that Arjuna thing yourselves, sorry. And gonna go no for 5-B. Da Vinci makes it clear, not even something that could theoretically destroy the planet would do it, The Counter Force would smack it upside the head. And the actual threats we get are never shown going for "destroying the planet", but doing something irreversible. Settling for 5-B as a hard base tier just doesn't seem too good to me, we actually have no clue how much power you gotta pull out of your ass to overpower Gaia and actually destroy the planet, or if that would be an actual requirement to be considered a threat to it. Far higher with half restraints off, Likely/Possibly up to 2-A works better for me. One of the beasts is even from Arthur's own world, so stuff that powerful can spawn on his side. Excalibur can deal with Sefar because nothing else can hurt it without Sefar nourishing from it, healing to some extent and becoming stronger. But it can still hurt her so yeah sure, 2-A at full power works.
Merem and Gransburg need to combine for Altrouge because two of the Ancestors are her bodyguards, and they think mutually assured destruction would be the only way to get rid of each one. Based on that alone, and that Altrouge is considered monstruous due to Primate Murder rather than just her own power, double that for her, Roa and Arcueid I can't agree with. But Altrouge should obviously scale full power Arcueid as she was the one to cut off her hair.
