I did some searching on Reddit to see if I could champion more people to our cause of either reverting or tweaking the current system, and found a workaround for those stuck in a DC travel loop:

Users jaqenhqar and drunkengranite both had input, and combined, the method is below:

Go to <insert drive letter here>:\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn
Open "FFXIV.cfg", and (if you have it) "FFXIV.cfg.old".
Delete the line "dkt_session_id" at the very bottom of the <Network Settings> section.

While it doesn't solve the root of the problem, it should hopefully mitigate the more pressing issue of the matter. As much as my roleplay loving self really wants to be able to visit my friends on Crystal and Primal (More Primal in this case), I think being locked out of a character due to technical reasons on the server's end is more of a pressing issue.
