I'm not sure it gains you anything. It has the same damage as a level 76 weapon. In all likelihood, it would be replaced at 78. Maybe it has some substats that makes it better? So instead of about 4 months, it is 4 months and 1 day while you gain those extra levels.

Besides, you can avoid all of that and just wait for expansion day and buy the upgraded tomestone weapon for poetics. It makes it pretty much obsolete too quickly to spend the time necessary.
