i mean, i won't dispute that.
whether it is or not isn't particularly relevant. it's not helpful to bring up third party content when discussing first party content, because it isn't first party content. it was also kind of strange because...well, bringing up third party content wasn't even necessary to demonstrate the point in question.
it'd be like, if to demonstrate that pf1e casters are more (or less) powerful then 3.5 casters, you pulled up spheres of power. it isn't really relevant if spheres of power is balanced or even good - it's not first party pf1e content.
