Well, with the new skill inheritance update that just came out, people have already started putting vantage on their Takumis, so yeah.
A lot of new quests too. Training tower quests have 36 orbs total but some of them look pretty hard.
Edit: even better, Takumi can be sacc'd to give close counter to any ranged unit.
Edit 2: Get ready for close and distant counter on everyone, vantage on everyone, brash assault for 4x brave weapon attacks in a row, desperation on linde and other fast squishies, wary fighter on every armor, and blarblade equivalents on every mage.
