I would be happy if they released raid content for catching up that are easy enough for a PUG group and also have progressive raids that are difficult but not unforgiving for a group of players that regularly raid together. There is nothing that says they can't do both. I fully expected Alexander to be raid-type endgame content but instead it was just more arena-based boss fights which, while fun, lack a certain feeling of adventure that I expect from interesting endgame content. What I want is that feeling of being in an endgame raid, whether it be WoW's ICC or FFXI's Sea and Sky, any of SWTOR's Operations or whatever MMO's version of it you'd like. Alexander is intense, but not interesting. I didn't go in and beat A1S/A2S and then be like "oh neeaaaat! that's really cool!" - Sure, when we won it felt great but that was mainly because we were happy we had finally beaten them and achieved something as a group, not because it was fun to do. Some of the most fun I had in Coil was T1 where there was a mini-boss, a decent amount of trash, and a boss that had actual mechanics that, while difficult, were not unforgiving and overly frustrating. It felt like a mini raid dungeon, and I loved it. Hell, even T3, which had no drops at all, was fun to run through because it was a large space to explore and learn the best route to the bottom. Then you get to T4 and T5 and it's nothing but arena boss fights from then on.Would you be happy if they releases Void Ark not on the DF and have second coil difficulty, so you have 23 people out to get you with their voices and shrieks.
I'm actually quite excited for the Exploratory Missions because it actually seems like the first type of content where my group gets to explore and discover, and it also seems like content that will hopefully last longer than a single patch cycle.
edit: said A1 when I meant T1
