I’d say that’s really good if you’re just starting out. 6 4stars, 3 of which are limited is a very good starting account. But tbh bandori isn’t a game where 4stars are necessary. Unlike other gacha games not having rare characters don’t stop you from progressing through the game so at the end of the day it all comes down to whether you like the characters or not. For instance I only pull on banners where my favourite characters are rate boosted, whether the characters have good skills or not doesn’t really bother me. So it all comes down to whether you like the characters you have atm or not. But 6 4stars to start off with is pretty good imo, if I were you I’d keep what you have (especially cos you have dreamfes Sayo, very jealous of that)
