You know I hear a lot about the arc of doom concerning ED, usually in parallel with the arc of renegade intentions of FD since before the KS era.
I often think of it like this:
Bloke waiting for a bus, he has come to understand that a bus is a mode of transport available to him that once a ticket is purchased, takes him to where he wants to go. He has studied the bus timetables and routes, and decided he wants to visit town centre and has subsequently walked to the relevant bus stop, at which point he has been told his bus will arrive and pick him up.
Now for the most part, he is able to witness several if not more buses both pass and stop at his bus stop, which he decides not to get on, as they do not go where he wishes to go. A destination that he has been reliably informed is possible to reach and the reason why he is at the bus stop in the first place.
He keeps waiting.
And waiting.
He is there for months, happily waiting for this bus come rain or shine, as the bus company is repeating his bus will be available at some point through the tannoy at the bus stop. If only every now and again.
Years later, the bus company announce they have stopped the service for which the man went to the bus stop, and would the man like to catch another bus? After he calmed down, the man decides that being as he is invested, and that his family have now left him due to him living like a tramp at the bus stop, he might as well.
Once at the outskirts of town, the man speaks to the bus driver and says "well this isn't anywhere near town". To which the bus driver replies, you just spent four years using our bus stop, then got the bus...what do you want from me? Of course, the rest of the passengers, don't want to admit to a similar level of embarassing commitment to the original premise laid out by the bus company, so they all laugh at the bus drivers comments. Most of them of course, have no idea where they are or how they got there.
Turns out, neither does the bus driver.
Personally, I'd give a bus company offering that level of service, not long at all.
It's not "Doom".
It's just survival of the fittest.
