As to Latin, I'm not sure what you mean by saying that its noun declension is "more regular" than in Russian. Overall I would say that Latin and Russian nouns are roughly similar in their complexity, from the perspective of a native English speaker, while Latin verbs have much more complicated inflections than Russian.
It is more regular because it is fully predictable from the nom and gen sing. There are very few exceptions. While Russian nouns are declined in unpredictable ways especially if we regard the stress.
For example, first declension end stressed nouns can have a stress shift in acc. sing.
водА - вОду
but
грозА - грозУ
in nom. pl. the stress usually falls on the stem
травА - трАвы
but there are several exceptions
мечтА - мечтЫ
the stress in other cases can be both on the stem and on the ending
травА - трАвы - трАвам
головА - гОловы - головАм
And that's just the top of the iceberg.
