I do not understand why I have spent that much time on ranked and I am still demoting and not promoting pass gold two, many of the time I blame my teammate and sometimes I try to carry, but the only thing i get from those are losses. Can someone provide me some tips and please analyse my and tell me what I could do to get to platinum? Thanks
