That's just how it is at first, trust me.
I was seriously freaked out during that first Feral Chaos fight, so I mostly dodged everything and stayed as far away as I can. But because I dodged more than I attacked, I sorta learned what kinds of attacks he throws and just how I can slip in between them. It helps that Firion has long-mid BRV attacks with HP combo too. He's totally one of my mains.
Also, I didn't win without any retries, so I'm not all that.
But thank you.
I freaked out when I saw the 100k+ HP on Feral Chaos that time. My BRV was, what, 1k?
But it was a real fun fight, especially since... well, I won.
SPEAKING OF MAINS, I just thought I'd share--these are my mains.
1. Firion (assist: Kain)
2. Bartz (assist: Gilgamesh/Zidane/Aerith)
3. Tifa (assist: Kain/Cloud/Aerith)
4. Zidane (assist: Bartz/Terra)
5. Terra (assist: Kain/OK/Cloud)
6. Vaan (assist: Kain/Zidane/Terra)
Well, they're my mains NOW. Might change in the future. In the old Dissidia, my mains were Cloud, Squall, Kuja, Tidus, and Jecht. I hardly use Jecht now, but we'll see later on. 8D
My fave assists are Kain, Zidane, and Aerith. On Aerith's part, it's mostly because she's a special assist and I love her.
...I'm not telling where I got my Aerith DLC (and all my other DLCs), though. So...
