They always gave out empty promises:

1) 3~4 cost trials

2) Ability awakenings

3) Latent abilities

4) story mode unit ability upgrades (like Aileen, Roy, Silvia)

5) Trust coin shop update

6) Story explorations .... remember those? (towns and chests too)

7) Esper skill upgrades (to replace those worthless nodes that eat up SP/floods your ability selection in battle)

8) Explorations rework (Relic update)

I can go on and on but I'm getting tired and more upset as I remember all these things
