I doubt it.

Frontlines is a mess, but it's also a mess that allows people with some classes to shine where they wouldn't be able to when everyone on the opposing team is focusing on them exclusively, it encourages teamwork rather than just rushing to burst down a singular person as fast as possible, and no one class is a potentially invincible juggernaut - which cannot be said to be true in Feast, which with the right support, some classes just quite simply won't die. You can focus all your efforts on them and it'd be for naught if your team setup isn't strong enough to counter it, unless you get really lucky.

So basically the idea is that in Frontline, know when to pick your fights. It's frustrating, particularly when your team abandons you to chase one person across the galaxy, but the core of it allows combat to be team-centric rather than showing off how easily say: a samurai can chew through a Black Mage's Manaward and nearly kill em in one combo for all to see. I know some people will likely rage at me for pointing this out, but Feast is not balanced. At all.

Doesn't matter which season you look at, when it's a 4v4 with tightly restricted role dynamics, someone, somewhere, is going to suffer for it. Is that a call for them to raise the numbers a little in hopes of maybe balancing it a little better? Possibly. Never knew it in its larger team state, so I'll leave that question to someone with more experience with the mode, can only comment about how it is now.

I do hope there is some future for it, but yeah, every time something's balanced, something somewhere else just becomes suffering. Feast highlights that more than any other mode, which isn't exactly gonna attract newcomers to it, unless they're dying of curiosity.
