Idk how long you have been playing Blu. But those hunters is fairly good and have high value in future if you 5* them. Such as Bibi, Yuri, Twin, Joy, Dino, Diana. How about aim to 5* some of them???
Lol well now it look decent. But still you have little bomber that helpful in pvp. In my opinion, your team is 4 out of 10. Suggestion: 5* Bibi, Joy, Dino for -def and more dps.
