re: "Why Runescape Has A Future..."
High time, indeed. Please continue this more positive tone, but not just for devil's advocate purposes.
There are players that have put Runescape on mobile devices already. But I do remember MMG saying that the switch to HTML5 (ditching the Java applet, I assume-- the applet, NOT the code) is how Jagex will be making RS available to mobile devices. They'd been working on such with FunOrb already, bit of a shame that FunOrb game apps didn't make more of a showing (not everyone is super enamored with Angry Birds and silly Facebook games).
re: How Much Is Too Much?
Interesting how the pendulum swings the other way, now. I can still remember how Gugge suggested that existing content, namely cities, get some reworks. Maybe we got this in spades? Players haven't done "one-stop skilling" in cities for a long time, and perhaps the Lodestone Network further aggravated this. However:
but there are no longer really any parts of the game world left that are simply there for skill training or gatherings
I still love the Burgh De Rott fishing pier for shark fishing... granted, mostly for Daily Challenges. It's separate enough from Temple Trekking that I'm not terribly distracted. I still like the Coal Trucks for gathering some of my own coal (especially with Achievement Task bennies). But I was always a player that sought out obscure niches, and I still do a lot of self-sufficient/subsistence playing.
Obviously there are still places like Yanille that have been largely neglected and feel like they exist for the sake of filling up space.
I've been in at least two clans/communities that used Yanille for non-combat training events (mostly bankstandable ones). I still love my POH, and I know a fair few number of players that have theirs there as well and still hold house parties. That said, I agree Yanille needs a little bit more love, but I hardly consider it just a space-filler.
I do agree with the sentiment about portals. I am still hoping, however, that Jagex will allow us to repair the the broken mini-ectofunctus in ghost ship in Port Phasmatys, and that it will be an alternate gateway to some new Eastern Lands content. They may never give me a further use to my hoarded ectotokens, but they can't tease me with Ak Haranu simply selling bolt racks forever!
