BPF has just dealt with that as I write but thats not a good instructor statement(if there is no wind we cant fly it then?!!). In an ideal world landing into wind is best practice but unless you have pre booked ATC with and anemometer in your chosen field you probably wont have much idea of what tbe wind is locally. There are other occasions when upslope may be preferable.
So are you saying landing into wind is not important then? If so, then I think you are wrong. Of course it may be better to land downwind into a huge field rather than into wind on a tiny one, and upslope may outweigh the wind on a sloping site. Flexibility is always going to be required and needs to be taught.
However assuming a choice between several small fields on a flat surface, taking twice the kinetic energy into your crash is not a good idea. There are usually plenty of clues to local wind direction and if push comes to shove you will probably be better off landing in roughly the same direction you took off in.
