On the topic of low level play/bans:
It seems to me that due to the standard bronze/silver bans (ie: Blitz, Amumu), a large amount of the people in said tiers are incapable of playing against these champs due to the lack of practice against them. I understand that the examples given are game-changers, a great Blitz pull or a good Amumu ult can change the outcome of the game, but in my opinion one of the reasons why they are so successful in doing so is that people ban them far too much and reduce the amount of time they play against them. I've had many games in which I was playing blitz/thresh support and the enemy bot lane stood there, unmoving, as I pull them in for my ADC to kill them. Some people are good at dodging and they are usually successful at dodging a thresh hook, but less so at dodging a blitz hook. I've also noticed quite a few players play very aggressive with their ability usage and positioning against such aggressive champions. In one such example, I watched as a Tristana used her rocket jump to leap over a minion wave, right into a blitz hook to pull her under the tower for an easy kill.
For the banning of strong initiators, such as Amumu, something that seems as simple as spreading out a bit more and positioning better is probably the best solution. However not everyone, including myself, are able to properly position in the right way to avoid these initiations from being extremely successful. It is one of the things that I feel is improved via practice, which due to the banning, is not achieved.
I bring up this topic as I just finished a game that started and ended horribly. I left blitz open after banning a request, and immediately two of my teammates start trolling and refuse to go anywhere near bot lane simply because the enemy team had a Blitzcrank.
In no way am I saying I'm far better than these people and I'm deserving of a higher rank than them, I am simply putting out an observation I've made in the recent games. What are your guys' opinion on this?
tl;dr: Banning the same champions every game is preventing players from being able to play against said champions due to the lack of practice.
