No. These games aren't actually as difficult as some like to make them out to be. There is a learning curve yes but if you take an hour or two to learn how it works (like pretty much any other game) then you'll be fine.
*nods* Their difficulty is over-stated. Whilst they do rely on luck at points (NG+ Four Kings can go die in a fire), as long as you pay attention to attack/defense patterns and the environment, and learn what stats to level up, it's like any other medium-hard game. If you're willing to put the time in to grind levels, you don't even need to learn the harder moves - block, attack and roll will get you through everywhere if you're a high enough level.
