Despite of the usual nagging about Airbus, I can only say that an A346 is rather easy to land. You fly it above the RWY and slowly reduce the thrust at about 30 feet +- a little bit, depending on the energy state of the aircraft (here the pantsbottom flying comes into play).
Landing the machine hard is just as likely or unlikely as any other aircraft. I found the 346 the easiest of all the airbusses to land, and I have flown everything except 318 and 380.
So in my opinion, the design is not at fault, and it is not only strong winds, that account for up or downdrafts. It can get quite bumpy in spring and summer, especially in Texas, if I remember correctly...
