Playing with and against the same champions every match is not engaging.

I'm so tired of every match I play having at least 3 of these champs in them every game. We all know they are annoying and some of them are just blatantly overpowered. I get that they all have clear weaknesses but that means nothing if teams can't capitalize on them effectively or that their strengths are so overbearing that We die or lose them because we cant do anything. I just tired of games being won in champ select. This issue of imbalance is never even acknowledged by Riot. I don't think they are bad or incompetent I would just appreciate some honestly. We as players know they enforce meta and play favorites. They are not Satan for it but if something is getting the kind of backlash I see on the boards and reddit everyday then acknowledge it.

My personal problem is that squishy late game champs like are useless now because of the competition and shorter game times. So why not acknowledge and change it?
