All the previous modules followed more or less the same pattern when it came to adding new content: a set of new dailies that progressively unlocked access to more content. You may not like dailies, but it was well done for what it was.
The new Elemental Evil content however, aside from the intro quests, makes me wonder how anyone could have ever thought that this was a good idea.
There are several new zones, and in each zone there are multiple quest hubs. At each quest hub, you get one regular quest which tells you to complete 16 hourly "tasks" before you're allowed to progress. There are only ever 9 tasks available at a time and they reset at the start of the hour, so you have to spend at least one hour at each hub to complete the required amount of quests, usually more.
The really annoying thing however is that you can never pick up more than four of these tasks at a time, and they all require you go to the same area. They are all of the "kill ten rats" variety (more or less), so you spend all your time running back and forth, killing the same mobs over and over again because the associated quests are only drip-fed to you: first you kill lizardmen because they are inside the mine you have to go to, then you kill lizardmen because they hang out near the sea hags you have to kill, and finally you kill lizardmen because you actually have a quest to kill lizardmen.
It took my pet tank and me over four hours to complete just the first map, during which we killed about a thousand mobs (there was also a helpful "kill any hundred mobs" repeatable quest that helped us keep track). I can't recall the last time I did anything that ridiculously and artificially grindy in an MMO, and I'm not even sure I want to continue to the next zone - which is more of the same.
