Not really. If they did the maintenance early morning, nobody in the US or EU would be impacted during prime time. Britain is 5/6 hours ahead of east coast. The maintenance could be from 3-5pm in Europe(using Britain as a baseline, though you can give or take an hour or two for further east if need be. Just shift the times), 10am-12pm EST, and 7-9am PDT. Boom. Nobody impacted(unless you count areas OUTSIDE of NA/EU).
Like I said, you could even put the maintenance an hour or two earlier and still be fine. Afterall, it's what all the other mainstream MMOs do. I don't see why FFXIV would be any different.
With all that said though, I'm not really all that bothered by not being able to play for 2 hours after work. I just find it a bit funny to see people acting like there is no way to avoid this.
