Shall is still used in English grammar :
"Will" means willingness and it is also the mark of "future tense"
"Shall" is used when making suggestions or when I am ready to do smth. in the future but this not my "will" or my" wish".
Mother :Jane, will you help me with the dishes,please?
Jane : yes, mom, I will [ it`s my will ; I`ll do it because I want]
If you use " shall" instead of "will" in the previous sentence, the meaning is different.
In my opinion both variants are correct:
will we go? - someone asks us if we intend to go in the future
shall we go? - someone asks us in a polite way if we want to go which may be in the future or in the present
