I have to admit, I really don't get the issue with the Forgotten Realms shaking events. I mean, I just played Storm Kings Thunder and ran Dragon Heist. Both are pretty solidly grounded in Forgotten Realms as far as modules go. Yet neither of those modules mention anything about any Realms shaking events, even though something like Storm Kings Thunder has you traveling all over the Sword Coast.
OTOH, the Time of Troubles gave us Baldur's Gate. Which, by all accounts, has been a rousing success. So, again, where's the problem?
I suppose if I wanted to run these long, drawn out campaigns spanning several years all set in the same setting, I might see the problem, but, 99% of the time, it really doesn't matter. Two years of weekly sessions all set in the Realms and not a single Elminister to be seen.
People blow this stuff way out of proportion.
