Why would that be stupid? They could easily make legacy-only worlds have different requirements on items. You may not have noticed this but they've managed to run simultaneous combat modes, different requirements on items is not a harder technological feat than that. Actually it affects a large number of items (in the pking world). I'm only commenting on this because despite what you may or may not think Jagex is clearly interested in putting a lot of effort into trying to get back old players even to the point of offering stat editing for your defence level. How long before Jagex says "hey, you can edit all your combat stats if you just please please please play runescape again"? This is not an effort to placate whiners who dislike EOC but still play it. They are putting in real effort to entice old players back to runescape, I'm simply pointing out things that will keep them away. A "nice shiny override to hide abilities"? Yes, I would agree with that definition of legacy mode. Which is why it won't do what Jagex wants it to do.
