There are lot of games that play quite different when you play on easy, especially one with good AI coding - I always bring up FarCry 1 as example which on hardest difficulty has specially clever AI, while on easy it's pretty much cakewalk.
That said, I don't think there's anything wrong with playing on easy per se - for example, my brother plays all his games on easy, and I've never mocked him for it - in all 30-35 years we've been gaming, he was never really good at it, and honestly never cared to be anything but casual gamer.
