What do you mean by real basketball tactics? All of the current tactics are certainly used in real basketball, with the possible exception of the inside box and 1, which I suppose was necessary to keep options more or less equal for the inside / outside focus.
So, what are you getting at? You want even more new tactical choices? Personally, I think there are plenty for now, what with the implementation of four (4!) new tactics.
Once I scored a basket that still makes me laugh.
