If you have every level you want planned out and you don't want to risk altering one here or there it probably is a good idea to wait, but even then not beyond level 140 or so. It's pretty easy to rank up vocations between levels after that point. On BBI you'll have to be careful, but Gransys shouldn't be much of a risk.
