I really think those Episode titles are fake on imdb.
I actually usually like the real world parts more then the fairytale land parts. So i would dislike an all fairytale land season. And i think there is still a lot more to tell in flashback even if everyone remembers by the end of the season. I think it would be pretty amusing to see the characters not know how to do things. Like how to use the stove or how to drive or where to go. That sounds like fun to me.
And how would Snow react the first time she saw Regina wandering around town and she has to pretend that she is still afraid of her. That also sounds like fun to me. It did seem like the Hatter knew things about both worlds though.
If they did one full episode of fairytale land and then one of the real world i would be okay with that. That might help them to be able to do a grander scale and more action in the fairytale land. Especially if there is ever going to be any fighting against the queen in any way. That might allow for more complex plots.
