im sure many are excited to see the future and were we have come from but what have we gained?

we have lost some old ability's that some classes once had. now some are back.
but what else of the past have we lost or rather is the past turning into the future?

ive noticed npc's guarding entrances to what looks like planned dungeons or instances?

im not relly sure what there for i know they only speak of that they cannot allow anyone to pass.

what im relly curious about is how much will the era's of past present and future will tie together. for story related events you can see past events.but i wonder if the dream of the nightmare was a future vision.suppose we wont relly know till the event happens for 2.0.

what is everyone hoping to see stay or go or be brought back?.

perhaps if our choices we made up to 2.0 where changeable would you bother to go back and change them?
.any thoughts?
