>How good is the story/lore?
The story is good, but it's the characters that carry it. It's not about saving the world all the time, which I think is a good thing
>Can I play old events or are they just gone?
All events are archived at their second rerun, you can read them whenever you want and you will get the welfare unit from that event
>How F2P friendly is the gacha?
Rather friendly I'd say. You don't need dupes of the characters and there's no weapon banner. Pity is at 200 rolls and you get that every other month as a free player
