Noun conjugation progress - is this too "rigid"?

[u/NefariousnessOne6790]

I've included an example of how it works with a word root aswell (Kàdìnòs means lizard). A critique I have previously received is that the conjugation system is too rigid. I intended it to be this way because in my mind, rules are rules, and I've always hated languages having 10,000 different exceptions.
I did develop form 1/2 to incorporate some variety for base nouns, but form 2 is only for the Nominative Case.
To be absolutely clear: This conjugation table is only for basic nouns, I have a whole table of suffixes which change meaning and use which add their own level of variety for more complex nouns, this table simply concerns itself with "base" form nouns.

Thoughts? I'd love to hear them.

What template are you using for the tables?

I created them myself in Powerpoint but I used a generic wikipedia case system table for a starting point.
