Need to address the Eureka in the room.

Adding it to 5.0 will seriously hurt the game

Does it? I only ask because I was told it's a vocal minority who hates on Eureka but since square doesn't like to reveal its info I can't assume it's false either.
Not that I care since after hearing that I already decided not to get the expansion: I couldn't last up to level 4 in that hole and thinking to get more of that makes me shiver in disgust.
