People who opt to focus on one element are also generally supposed to work on a secondary team specifically to handle their weakness.
Wind doesn't need much to get you through thunder events. You already have free/practically free access to -30% atk/-15% def through Cybele and Zephyrus. If you manage to have rolled Oberon, congrats, that's the debuff core of a SSR-less wind team for a launch player (me). (how I managed to roll 16 SSRs, but have none of them be of 2 of this game's 6 elements is bewildering)

Though I probably should stop using Zephyrus by now. I'll probably go... I dunno, Joan/Cybele/Oberon/Ithaqua/Wind Ramiel here, I suppose. I should be fine if I attack on the first two turns to get through the first two specials, then start applying debuffs right? Then use Joan to tank the overdrive and hopefully be able to full burst then.
