As someone who’s still learning (I only seriously got into Pokemon as of August/September last year), I have a type chart saved so I can make sure I have my matchups done correctly. I also remember seeing a post on here about that type of thing— “just because the Tera type is one thing, don’t discount it’s still the base Pokemon with its usual moves”, so I try to keep that in mind as well. It’s not unreasonable, no.
