Well yes and no.
Think about it on a raiding standpoint: Technically, they could have made Alexander the same was as Coil was in 2.0. But they wanted everyone to do the story and Savage Mode was introduced as regular content for hardcore people. It follows the general guidelines that were established when they first showed off Savage for Second Coil:
1) A group is going to go in there and not be able to simply DF it; you will need a permanent party or a Party Finder.
2) This is not easy content nor is it casual content. This was made to test your mettle.
3) This doesn't really go into detail with extra story. This is just harder requirements.
The only caveat to that is that Alexander introduced the higher tiered gear that you can get from Savage. This was not the case in 2.0 Savage and, to me, has caused a lot of headaches with the whole itemization level we've seen in 3.0 (That's a story for another time.)
PotD actually follows 2.0 a bit more than 3.0, with the only fact that you probably are going to get more Silver/Gold from the higher levels. You don't get extra gear, you don't get anything story wise you wouldn't get from doing only up to 100, and it's a test to see how good you are. It's like an extra set of goodies for you to do.
To me, this follows the same logic they've followed in regards to 'Savage' content. If you think about it: Alexander is pretty damn casual really. Sure, the fights were a headache, but once you figured it out, you could plow through. PotD will be the same way once people get the required gear level to flow through most of it. And even then, it'll be more challenging than the Alexander normal stuff because you will be exchanging your + number for gear when you want, which will increase the difficulty of your runs due to the lowering of stats.
I don't know. I don't have an FC that has many members that are active and 4 man content together is hard to do and I do most of my stuff in DF. This doesn't phase me in the least and I've come to accept that the Savage portion of this game won't be done. I just don't get upset about it, really.
