After Secrets of the North, and seeing what's coming with Desert Treasure 2, I am extremely worried about the direction that the OSRS story/world is going to be headed in. Most people quit RS3 because of EoC, for me it was the direction the story took.
One of the things sets OSRS' setting and storylines apart from other MMOs is that you aren't some great big chosen one (World Guardian), you're just an adventure bumbling through various crises. You don't interact with the Gods directly, and you sure aren't traveling across insane amounts of planes and time to stop a universe-ending big bad.
I hope that Jagex keeps OSRS a bit more toned-down, I don't want Guthix to have been hidden under Lumbridge all along, I don't want any of the Gods to get killed onscreen, and I sure as hell don't want a new age with the Gods directly returning to Gielenor. Please don't make us into some generic chosen one, not all modern media needs to have conflict at a universe-ending scale.
