gold 1 (mid plat MMR) Bard LF ADC

I have been playing and mastering Bard. last week I had a wonderful run. I went like 30-10. Once I went for promos to plat eveything went to shit (as it usually does). I hate blaming other players, but i have noticed that my ADCs are really struggling. I feel with some voice comms we can climb far.=)
