No it's not going to be nearly impossible to get...also the achievement will be changed to reflect the change from Ranks to Grades.

With everyone being reset to Ash, it's roughly 90 pips to get to the highest Grade (same as it is now) and is not that much different to the way it was when the game first launched and a lot of us managed to get the Rank 1 achievement back then, so I don't really see that it's going to be any different now.
