The ideal for me is to give the reader of the translated text an identical experience to that of the reader of the original. This is not always possible and so we have to make best approximations. For example word order can often mean you get a surprise at the end of a sentence in one language but not the other. A French sentence will typically tell you all the incidental matters before getting down to the nitty gritty. In English we tend to go straight for the jugular.
Future tense I'll admit is a minor difficulty and there are plenty of similar ones, like our subdued (nowadays almost entirely absent) use of the subjunctive. Fortunately for me I don't have to deal with a language that has also declarative, energetic, generic, cohortative, dubitative, eventive, hypothetical, inferential, jussive, optative, potential, and presumptive moods!
OK that's me finished with this topic it's too much like being at work
