Well, in an arena, not have an AoE BB or SBB is a huge point off, becauss it would be harder to wipe the team out.

But still, I think if paired with Hadaron lead in arena, she can easily OHKO an enemy's unit. And if the team does not support enough BB gauge, her BB can still help fill out the BB momentum of others, so her BB is not entirely wasted,
