I dont know about CT really maybe just with the roulette, but about Bahamut Coil and Ex primals i wish they just upgrade everithing about these to the max level, even gear with current ilvl.

Most new players complain about the amount of stuff you have to do at 50 to progress to HW, why would you want to add CT etc on top of that? It would only put them off playing even more.
I dont think anybody want the old content be a pre-requisite, but make it revelant so theres more thing to do. This its the first MMO where i think i had more things to do before an Expansion comes out. (dont even start with "just go and do it" because isn't that easy find a party for those anymore, f**k isn't even easy to find party for Bismarck EX now xD)
