Ranked bugg

so i was just wondering ...is there anything wrong with ranked games becasue out of the 10 games ranked i play at least 8 people go afk before hitting lvl 2 and they never recconect glitch of course makes us lose but the funny part is that its only at ranked...normals aram poro king everything works just fine but ranked...i dont play ranked that much but when i do there is always someone going afk if riot could check that, it would be great
