English grammar is considered pretty diverse, especially about tenses. It takes quite a long time to properly study it. If we talk about the prospect of communication, it might probably not worth so much to delve into each of the tenses. Native speakers can easily understand you without complex tense structures. Please note that we are talking only about "spoken English." However, if you need academic English to write literary or scientific articles, you may need to use a little more tense structures. I agree that some tenses in English are extremely rarely used. But from my point of view, it would be nice to get acquainted with them, at least to get a complete picture of English grammar.
