Yeah, but it doesn't matter if its weaker or not. we don't have a rank to distinguish a stronger Rinnegan than the one we'd get and don't plan to introduce another rinnegan that is stronger, because there is no rank stronger. if we're talking about facing Otsutsukis then we'd probably already be outside of the game's intended scope.

but really, there are different types of rinnegan? that is just as frustrating as mangekyo sharingan. if there is no consistency, we might as well just make stuff up to get a custom rinnegan for what we need anyways. its not as if I'm going to hold to canonical mangekyo either, since I'd argue that Kamui and Kotoamatsukami are too powerful to allow, at least not without nerfs, and I have my own mangekyo ability planned.

also define "advanced abilities" of the rinnegan as opposed to "normal abilities", Six Paths rinnegan by itself is very advanced compared to everything else.
