I was kinda hoping they would reveal how rewards would differ from Normal and Hard Mode.

I feel like if they plan to make them the same then they run into two issues.
Raid groups can easily build their gear up through normal mode and then tackle hard mode once they are properly geared rather than spending time challenging hard mode

However they can easily prevent that through two means

Either
-Normal mode won't drop gear and can be done freely much like the 8 man story mode dungeons
-Hard mode offers double the reward drops but this can be exploited in terms of people paying gil to have a larger loot pool from hard mode

I do just hope they consider the idea of making Normal mode a "Story mode" for those to enjoy since if they don't decide how to properly differ the rewards from both options even though people want a challenge, they will just do the easier one to gear up quicker.
