5/5 Saber wasn't particularly good or worthwhile until the merits translated into extra attacks. (Pre-Etoile+2, the difference between 5/5 and 1/5 was ~1.5% average DA over the duration of the effect).
The only reason to have Fan Dance up is ... soloing .. and then, full-timing it is mostly detrimental if you're worth your salt. Waltz recast is generally a non-issue soloing, so it's a completely useless upgrade.
So, you might as well take your extra 5.5% DA and call it a day.
