I agree you have options, but I think the main reason for complaints is the frequency of the more advantaged team picks in unranked matches. For example, some nights I'll play match after match vs teemo, Darius, chogath, singed, jax...many times it is a random composition of those listed. Now I'm not saying you can't beat them, but when I picked vlad let's say I did not plan on Darius, teemo, and singed together. But everything can be countered and anyone can play those champs so what's one to do other than try and counter what your against.
