I only have one SSR in Brahma and I dont even have a powerful Thunder Eidolon. The only three I have are a one-break Mastema, an unbroken Ixion and fully broken + max level Meng Huo yet I'm still demolishing Ultimate. Ragnarok's well out of my league though. I shall be glad with the Thunder Crucible event rolls around, my wind team's one of my strongest. That Snowman Stomp attack is a real piss-take though. It's essentially just a reskinned version of Dizzy. Her Rage Overdrive is pretty damn strong but because of my damage output, she can only use it once as she's under 1/3 HP when she uses it, and Mordred's debuffs completely nullify that regen she gets.
