I'm not even going to humor this with any further response than just.. what the fuck?
Because of the Fate downplay that people love to engage in unironically in SB, you have people straight up lying about how ill capable Servants, Mages and Lostbelt Kings are because of "consistency" when it never made any real sense at all.
Lostbelt Morgan is easy to downplay because all you have to do... is not even bother looking at any of the actual spells she does, just pretend Rhongomyniad takes ages to launch and she's somehow squishy as shit. It's how you had someone pretend Tristan is a "one trick pony" in that Tristan vs. Izuru thread despite it's not hard at all to find feats for the guy that makes him body every Lieutenant with ease.
