I didn't say to remove the Spellplague timeline altogether. I just suggested to put it on perforated paper so I can tear it out of my 5e FR book. And burn it.You do realize that would be 17 kinds of business unwise, right? Setting up a timeline where people can play at any point of the timeline is the way to go so fans of all eras can play in the Realms as they want.
As for business unwise, well... I used to buy every single FR book during the 3.x period. I spent quite a bit of money on them. So from my own personal business point, it was quite unwise for them to stop producing FR content during 4e.
