Lets start off with craftable minions from extremes Stormblood we could craft minions with the extreme materials, Shadowbringers this was taken away from us. Now those minions seem to be relegated to PVP Limited time series see the rubilite minion a shadowbringers trial in endwalker PVP reward.

Next stormblood gave us Eureka and Heaven on high. We only get one of these per expansion now. Shadowbringers was Bozja which replaced Eureka. But no replacement for heaven on high though End walker we got eureka Orthros no replacement for Eureka or bozja.

Hard dungeons removed since shadowbringers. these gave variety to expert roulette. Devs gave some stupid bullshit excuse on why they removed them.

Class quests for every class. Role quests are supposed to be there replacement but role quests dont feel like they add to a class at all. This is a loss of additional lore.

With the trial stories being MSQ we lost yet another story to the game so more additional lore lost.

Allied Beast tribes has been lost W lost a cool cutscene of all the beast tribe coming together to do something cool and an extra reward from them.

6.4 they broke there cycle of craftable ex weapons was hoping for seat of sacrifice or emerald weapon to get a glowy version of there weapons. This did not happen as of writing this.

As of writing this as well. There is no signs of an 8th trial for this expansion. Stormblood we had Gilgamesh and rathalos. Shadowbringers we had Varis. endwalker we have umm nothing so far.

We also have lost the third map dungeon that was added with stormblood and removed with shadowbringers and endwalker.

I know theres more im missing but ill leave this here for you to discuss.
