Dynamic queue 3 man premade abuse

I'm sick of people abusing the DQ as 3 premades. Literally in 90% of my games in the past 5 days i'v been matched against 3 premades while having 2 on my team and i as a solo player was stomped each time simply because they are nonstop 4 man bot. Please fix this shit or bring back the solo queue. I'm incapable of carring low plat atm while last season i could'v easily carried in diamond. After getting my other acc banned now i'm forced to play on this one and i can't get it out of this shitty mid plat elo.Its a nightmare!
