Training mode is indeed where this genre needs to address the issue of diminished gamer skill compared to the arcade days / 90s. Fighting games should never compromise their inherent steep-ish learning curve (assuming they haven't already) because then you undermine the entire genre (see: criticisms of MvC3, SFIV, MK9 et al). A fighter with Wiisy command inputs is a BRAWLER (like DBZ or Naruto), not a fighting game per se. This should not be forgotten.
