That's not to mention that Spanish is deletive so those sometimes subtly different verb conjugations are often the only way of conveying the subject of the sentence. It seems much more optimised for speaking rápidamente than listening, especially for non-native speakers.
If you were designing a language from scratch you also wouldn't choose features like the unnecessary grammatical gender (even though it's relatively consistent and easy to get right) and the b/v distinction in the orthography that's unpronounced in most dialects.
On paper it's still a far, far better auxiliary language than English though (I wouldn't be surprised to live to see a day when most people worldwide speak a regularised English with much more basic grammar and sensible orthography one day though; it's easier to build momentum taking the second language people are most exposed to as the starting point)
