Dragon team build

No cause having the same skills is not bad by itself and In Dragon emblem's case it's not a bad Idea but try to mix it up with sacred seal or B skill.

Warding Breath is also an option on some dragons like Nowi, just good luck getting the Legendary Ikes to run it. Aside for the free one, he's a limited unit in comparison to Brave Ike.

As for QR... it's just that good.

It might work well for PvE content, but for Arena I'd agree that it's kinda dumb. A lot of these units have better meta builds than Steady Breath and QR with Lightning Breath. They're also more interesting.
