I would LOVE some more 8 man dungeons. Sure, we get CT and we get Coil. (The latter I personally don't bother with because... statics are not personally good for me and that's pretty much the only way people progress through them).
Outside of coil and CT we have just 2 old story dungeons that are 8 man. We need more content like this, yet designed in a way to be sometimes like coil (normal floors with mini-bosses, final floor with end boss) and sometimes like CT (mobs, boss, mobs, boss, ect. til final boss). I say to use both existing models of endgame 8 man+ so that it doesn't always feel like you're running the same thing. You have to change it up or else it feels stale, how about a whole new approach. Who knows, maybe have a boss fight in the middle of a floor/level like some of the older dungeons do. Don't always use the same progression path. All dungeons don't always need 2 mini-bosses and a final boss. How about a more interactive dungeon, maybe some puzzle solving where the party needs to split up temporarily before rejoining. (just throwing ideas out there)
I'm just saying, we need more dungeons like CM and Praetorium. Honestly CM was a fairly decent design, there were several instances where party members had to interact with an object (or objects) in order to proceed in the content or make the content easier, this even was included in 1 of the boss fights and I actually love this mechanic (It's a really great design, only made difficult by brand new players that ((or normal players that just..)) cant follow commands). There definitely should be more of this.
While I don't mind the current theme of "trash, mini-boss, trash, mini-boss, trash, final boss", why does it always have to be this pattern with normal dungeons (and HM)? Change it up! Not all dungeons should have the same basic layout in my opinion.
FFXIV has been out over over a year, lets do more with it. Expect more! Think bigger! More creativity!
Come on SE (Dev team) I know you can do it.
