I wouldn't go so far as to say any should not have been made, they all appeal to somebody. However, whilst not the whole game, I would say Blizzard should not have produced the latest expansion for WoW. The game is too old, they have oversimplified it to death, seem to have run out of good ideas and now it seems like flogging a (nearly) dead horse. It's just, 'ere we go again, more of the same. Time they left it to the die-hard players, until it stops making money, and did something all new.
