Overall, I think the game mode is pretty fun/relaxed. It doesn’t feel like there’s a meta loadout being enforced, and for the most part, you have the freedom to bring whatever you want to the mission.
There doesn’t really seem to be any failure condition either (other than maybe the first objective, but I’ve never managed to fail there).
The pity system is also nice to have for anyone who doesn’t have the time to farm or has terrible luck and the event cosmetics also look really nice.
