I like the concept of phasing ok.

I think they should have done it as another mentioned so when done with all quests, you are in the case of "NO PHASE", which just makes sense, as everyone eventually ends up there, why not have the final stage be the base case.

I don't mind the break in autofollow to much, have gotten use to seeing it happen, then stopping and hitting slave key to move them up to me, and i continue on. Irritating but can deal with it.

I hate hate hate hate the new linear nature of quests though. I hate not being able to jump ahead if I feel like it or an area is crowded.

And the quest designers that put in stupid ass quests that are required to continue, yet have a low drop rate or very few mobs should be slapped, a lot...

Yes lets funnel everyone on the exact same path, yet have a quest that only 1 person can complete per 5 -10 mins. SO others have to simply wait or worse yet becomes a ninja fest.
