3. 9 is an odd number to pick, most people agree there are 12 or 16, but you have (multiply as appropriate) past, present, future, simple, future-in-the-past, continuous, perfect, perfect continuous, indicative, imperative, subjunctive, active, and passive forms.
Russian on the other hand has 2 grammatical tenses (past and non-past), and 2 aspects (perfective and imperfective), as well as a couple of forms constructed using auxiliaries (immediate future, conditional). It also has gerunds and participles, and all of this before we even start thinking about verbs of motion.
4. Russian does have the concept of specificity in some cases - in particular there are some cases where the genitive can be used instead of the accusative to indicate indefiniteness.
Definitely 0/10 for recommending learning Russian, except as an exercise in masochism (10/10).
