Getting declensions right is a pain when trying to write Latin, but of reading it you can often just ignore them entirely and work it out from context.

Of course you have to basically memorize the common things but those are all non-standard anyway.

Are you sure you are actually understanding the subtleties? I can definitely read latin and work out what is meant. But when I read my native languages, I can tell that there's A LOT of meaning hidden in subtleties that I would definitely lose if I were to analyze sentences only through etymological meaning of each independent word, to say nothing of the pain of having to parse ambigueties:

e.g:

Ambigueties: "Defended Warrior" - "Warrior Defends" / "Bellator defendit" - "Bellator defensus"

Subtleties: - "Defense! Defense!" "Defend! Defend!" (Basketball vs war)

- "No good", bad? Or bad/neutral?

- "Do you take me for a fool" / "Do you think I'm dumb?" (Accusation of cheating vs Earnest)

That's not to say you don't have the tools to derive meaning from context and parse ambigueties, but if you are simultaneously parsing syntactic ambigueties, then you have much less energies to parse semantic ambigueties and to try to work out what idiomatic phrases would have meant.

And the effect is multiplicative, if you have 2 declensions you don't remember, you have 4 combinations to parse. Multiply that by 2 possible meanings of the phrase (or more) and you have 8 meanings ( or more).

Sure, you can read somewhat, but I'd be skeptical as to how much you can understand what you are reading, sure it's more than chinese since we share a lot of roots, but there's still a lot of meaning that is missed, and knowing declensions is like level 1, it doesn't guarantee you will understand latin either.
