7. RM
I think his vocals are poor his singing sounds more like slow talking rather than singing I think he is meant to be a rapper
6. Suga
he has potential to get better but like RM He is better off as a rapper
5. J Hope
his vocals are ok he has a very soft voice he has lots of potential however he is not as strong as the next vocalists
He is good he is a good lead vocalists however he is in this place cause the next 2 vocalists have improved a lot from debut, Jimin tends to strain his vocals a lot
2. Jin/ V
I put them in the same place cause I think they both improved well as for their weaknesses, V tends to yell a bit and Jin he lacks versatility as I think he suits slower songs
he is stable and deserves his position as a main vocal he'll get better and better however I think he lacks emotion is his voice
