Well, three things come to mind. We could:

1. Nerf the %scaling across the board for Summoners using Youkai spells, down from 340.
2. Give Summoners using these abilities a different formula, one that involves SWA.
3. Specifically change the formula for the Youkai spells commonly jacked up to enormous levels.

Either way, I find it important to mention I don't think any scaling needs to be touched for the actual summons themselves.
