I struggle with the "don't fall off, you idiot" mechanics a lot so I sympathize. Titan EX and Leviathan EX especially cause me (and undoubtedly my poor party) a lot of frustration.

But like everyone is saying, that's just part of the fight. It's up to me to learn how to deal with that just like it's up to me to learn to avoid Landslides and Bodyslams. Making it all easier by ditching certain fight mechanics (unless those mechanics are super broken) is no fun just because a few of us hate it.

Because let me tell you... the moment I got the Titan EX rotation down and stopped falling off was a moment of triumphant for me. And because I finally learned to avoid it, we won! Dumbing that part down would have made that victory way less satisfying!
