Looks like I will be rotating my support engines.

Astra previously held Kaboom -> Giving her The Vault because I love the faster Quick Assistst
Yuzuha previously held my W5 Weeping Cradle -> Giving her Astra's Kaboom because it's still very good for her.
My W5 Weeping Cradle goes to Lucia.
All the Gameballs I planned on giving to Lucia will be merged into Soukaku.
