The quests are the same as live EQ, but mostly made a lot easier due to being able to make a DZ of many zones with the exception of some things like Quillmane in South Karana and Lucan in Freeport. The resulting items are in many cases very different from live EQ though. For instance, the SK and Pally epics are 1h slash here, and the ratios are 80 45 on the SK, the cleric epic has a DD proc with a mad proc rate modifier (400%ish) and a much better ratio, like 40 30 or something.
If you want to see items in the game that aren't available yet like items from Kunark onwards, just go to the baz, type /buyer, and you can search up any item from any era and see all 3 levels of it.
