I ran my team to level cap in the new zones. They are very pleasing to the eye and well-thought out, colorful and with a taste of underwater. Crafting is cool too, you craft only blue-quality items for all slots, and later when you accumulate enough of crafting currencies you get to craft amenders which update crafted gear to lvl 65 so you can attempt expert dungeons. I have not been doing much dungeoning myself in the new expansion, and currently taking a RIFT break and toying with EVE, but you can expect some boss mechanics that make them challenging to box. Closing major Rifts is still relatively easy, and the new minion system releaves the strain of harvesting to level crafting somewhat (especially with you having access to five toons). Well worth it and fun I'd say, and it is FREE, lol.
