I'm a native English speaker and taught myself Spanish. I focused heavily on grammar and verb conjugation such that I can explain verb tenses and their uses to someone else learning Spanish, yet I struggle to explain the same to an English learner. Either I didn't care enough to pay attention during my English courses or it's not taught.

Of course this is just a stepping stone, but why try to duplicate (or more) everything when what you most need is proper sentence structure in the present tense and vocabulary.
Although maybe there are some languages where this is not true, not the ones I studied (briefly or not). But in my experience it is also true for people speaking bad German (talking mostly self-taught or from basic courses, not for white collar jobs with large amounts of written text) - perfectly understandable, just no tenses.
