You guys have the same number of cases and genders (and thus possible endings) as Russian (well, technically Russian also has a residual 7th case, but it only shows up in a small number of individual words - I'm sure you guys have that too).
It's not too bad for a speaker, just really kicks the learners in the butt
And really, what you get for it is some awesome freedom of poetic/emotional description that's simply not available in a lot of other languages. Slovenian is one of the most expressively nuanced languages in the world thanks to that and I'd rather it not lose that
(also, I guess being a linguist, I can't help but see this all as a good thing, haha)
