We'll have to wait until it's out to see. The statement that they want to minimize grind? Hoooooly crap, that's the exact opposite of what RS was. To get to the higher levels and max a skill, it was basically a mental game of sticking to the best xp/tick strategies, which could still take a month or more to max one skill. That was after they had introduced a bunch of new things. The original days? It was a third job on top of it being the second job to do it in months.
It was also really fun for being so simplistic and had a good mix of self-aware humor, so I have hope for their new game.
