Not at the moment. Wasn't really advocating a level cap to be clear, just that to expect one isn't so far-fetched. Like you said, some benefits could be the ability to access new storyline, equipment, enemies, skills, higher level areas (which can all arguably be done with or without a level increase). All of this seems more fit to be put into an expansion once the core game has been established

If you were to ask if I wanted them to increase the level cap in the near future, my answer is no.
