They reason people like THJ was because it was solo friendly play at your own pace. This isn't solo friendly.
People that have NLed the beta and have 10+ days /played time already, that have been chain killing increased spawn rate OW raid mobs uncontested for weeks(won't happen if the game isn't dead), effecting getting more loot per day than people will get from instanced raids in a week, are only able to kill mobs solo 1) with a Cleric, eliminating 2/3s of the potential builds 2) Really slowly, keep in mind the setup that kills Naggy in 30 mins is going to translate to killing AoW in like 2+ hours and realistically won't be possible.
