Parsers add replayability for casual players

[Caurcas]

I would make the argument, OP, that you aren't really casual. Not that casual players can't learn a rotation and do decently in groups. Nor that they can't enjoy increasing their ilevel. But the flaw in your argument is that a truly casual player doesn't care about those incremental changes in their numbers. Once you start doing that, you're getting in the realm of the midcore to hardcore.

It's like with any hobby. There's a spectrum of involvement. Once you start getting into things like numbers and optimization, you're not approaching that hobby with a casual mindset anymore. It doesn't matter how much time you play.

People like seeing progression in video games, in 14 at level cap increasing your #s is that.
