I think that is only a minor reason for not exploring. Yes, everything you need is there, but even if that wasn't true, there just isn't any real incentive to explore. There aren't hidden treasures to find. There aren't unique and interesting areas on a map to discover. Sure, finding a nice river or mountain or canyon or something is nice, but not that big of a deal. There just isn't anything truly unique to find or see.That being said it seems like the over-arching sentiment is that cities offer so much value there isn't a need or reason to explore. People like exploring so I still suggest there be some incentive structure behind it to make exploring worth the effort and time.
Most games with good exploration give you some reason to do so. Part of that is through hand crafted maps with will designed areas to explore. You can get that, to a point, with have crafted maps in this game, but most use randomly generated maps. Try playing a will crafted map from someone like Grimlock and I think you will find explain to be worthwhile. Or games with good exploration do it through use of hidden secrets or unique items that are hard or impossible to find without exploring.
In the end, this game isn't designed to offer really unique areas. Maybe they will do something with the legendary/unique equipment they said they will add. Perhaps making it so you can only find one of each somewhere on the map, without it being just RNG in any container, though I doubt we will see that. And I don't think an infinite map adds anything beyond just a large map. You get the same kinds of locations, so it doesn't improve exploration.
