For example, you might like Star Trek, and you might like NCIS, but would you really like to see Star Trek give up the space ships and become a crime drama?
if done well, sure. (we've seen the trek franchise have problems when it comes to ship based shows and some would say the best of the franchise was a show about a space station)
is MoP a reaction to ToR? if i had to guess i'd say no. if anything the WoW guys will check out ToR and take what works and add it to WoW (if applicable).
