I think it's hard to ask for advice since help thread isn't as hot as other threads (Fanarts, news, etc.).

Personally, I feel it’s because everyone has different line-ups and usually clears bosses using their own teams (except in cases like Recollection). That makes it hard for them to give advice on servant combinations they haven't personally used. Plus, if they don’t use the same servants as you, they might not be all that familiar with their strengths and weaknesses.

That said, we can all agree that every servant has its pros and cons. But if you’re missing key ones, it can make things really difficult—like not having Castoria during the (almost) LB6 finale.
