FF14 been around for 8, with no end in sight. Well I mean the next expansion is called Endwalkers, but there's like 4 more planned after. We haven't even got to the Magus Sisters or Zero-Bahamut. Anima will be the trial in Endwalkers, and we go to the moon; but that's also gonna take Cid building Ragnarok. That'll be fuckin awesome. Right now the 3 hardest fights are Alexander Ultimate, Leviathan Unreal, and DR Savage. Funny thing is Diamond Weapon extreme doesn't come close to any of them, even though that's the newest shiz. And Diamond Weapon literally goes full queen xenomorph and starts jumping around like a monkey on crack and starts to OHKO peeps in it's path.
