While making the game have the ability to competitive is important, it is by no means more important than making it accessible for everyone else, from new player to experienced player-but-not-pro. Most players are not going to touch the competitive scene, and many will rarely go online. This isn't really about "noobifying" the game as it is making it fun with a complexity level that most people can recognize and practice without feeling pressured to master it just to last more than ten seconds online.
Basically the competitive scene needs to be considered in development, but it should not be the main focus.
I'll second this.
