Progression pits are like: Start by being killed and need to get more heals/hp/tank/def. Now I'm at "time is running out I need more dps"... Is it like this on the endgame as well?

New player here, My team is now lvl ~160 stuck at 30-05 for a lil while now, due to time running out.

I tried replacing Adding in Lisa instead of Dian, NEO and Merlin, but it's no help, this is my higher dps team now. I can't clear the stage due to dps, I don't do enough damage.

I would love to know if this kind of wall is "how it goes in the endgame". As this happened in two out of three story paths (hell) and in dungeons too.

I know I can overcome it, farm better equipment, wait a few days to get the mats, done. But... it's in my opinion, a boring wall. Is it like this often in the edgame?
