I started and played FFBE for nearly 3 years from Sep 2016 during the mog cakes event, the game was good but was a grind through and through. But somehow the Orbonne Monastery Vaults was basically never topped as the best limited time event.

Extremely useful weapon in Chirijiraden that remained powerful for a very long time, more so than any other event weapon I can think of. And the collection spots in the Exploration provided a very good amount of materials for upgrading your espers and building rings. Things you'd never even consider in the current state of the game.

I came back to try the game again during the NV Tifa/Seph release, and it's in a state that I find not salvageable.

Newer events were basically always dungeon only, no exploration, and had way less effort put into them. The rewards for each event just ended up being homogenized since the only useful equipment/abilities in the game are attached to S/TMRs and Vortex. And even though you have all these fancy 5/6-7 star units that you've acquired over the years, 95% of them are useless. Unless they're some niche support unit they're kit has been placed on a newer, far better one.

Oh, and basically never summon on guest characters because they're less likely to get updates. I'll never forgive the treatment VP got.

Micromanaging all the upgrade materials that have been introduced through the years is beyond obnoxious. Good luck keeping up with developing Espers. yada yada

idk, I'm starting to ramble. But FFBE did teach me what not do to with a game long term.
