[Help] Returning player — are my teams outdated?

Hi! I recently came back to the game after quitting during 1.X and honestly I feel pretty overwhelmed with how much new stuff has been added.

I originally came back just to pull Brant because I really liked the character, and I used the Astrites I had saved before quitting. Right now all of my 5★ characters have their signature weapons, and my Brant is S1.

I’m not sure if my current roster has become outdated or if the characters I invested in are still worth building around. I also don’t know if I should start pulling for an entirely new meta team or if there are newer supports/sub-DPS characters that synergize well with older units.

I’d really appreciate advice about:

• which of my characters are still strong/current for endgame content
• what characters should i pull
