first of all, new players shouldnt be playing ranked yet, in reality you should get about a year (if not more) under your belt before going into ranked (ranked means "im better than you and ill prove it" ) so if you're a noob and get, as you say, "pigeon holed" into bronze 5 then guess what, thats probably where you belong since you decided to play ranked as a noob instead of gaining legitimate experience and learning ALL the champs and not just the few you have learned to play in your first month or so since you will be facing almost ANY champ and should know how they work in order to counter them properly
secondly, i find it rare that a champ gets nerffed right into the ground (though it happens) but should that be the case you should be able to play multiple champs, not just one or 2, so if anything it would only help you come out of your comfort zone and play other champs (hence free champ rotation, its not just for noobs, after over a year of play i still use free champs as often as possible to help me learn champs i couldnt picture buying)
and 3rd but not least, new players lacking experience make new players that lack experience their own worst enemy, not riot, i mean, really, like anything if you are inexperienced then you wont be as good as those who ARE experienced, thats why ritos matchmaking takes all sorts of things into consideration to keep you playing with people of your caliber or as close as possible, and there will always be tough matchmaking decisions, like when that gold 2 duos with that bronze 4, pretty tough to match up all opponents easliy in that case
and i cant even begin to see what you mean by P2W, at best i understand it like this : i PAY my time to buy experience which i inturn use 2 WIN, PAY 2 WIN, but thats not what pay to win is, so please, elaborate, because other than a few select skins i see no form of pay to win, and even then those skins just give you cheap tricks, harder to see abilities or a different animation on a kill shot compared to a normal shot, neither will ensure victory, probably just make me worse since im relying on parlor tricks and not ACTUAL SKILL and champ knowledge
Can u even give an example of a sport where experience and practice doesnt help you get better? or for that matter, a sport that has tournaments on a professional level where noobies enter and lose then turn around and say : well that wasnt fair at all, they have experience, i should have a chance at winning!
i doubt u can give an example because thats not how sports work, u put ur kid in minor league so that after YEARS of play MAYBE hell have enough experience to join a farm team where hell have to do very well before getting picked up for the majors, and even then your child, who is now grown, might not do well on a professional level
thats what league is, an eSport, so if you treat it as such everything makes perfect sense
and like any sport the rule books get changed, you might not agree with some, or even any of the rules, but those are the rules and if you want to compete you need to abide by them
now if your complaint was something like, people with toasters shouldnt be matched up with people with super-pcs then id agree, newspaper shin pad kids without shoes shouldnt play adidas shin pad kids with shoes and expect the same results or a fair game, but it still doesnt mean they are gonna lose, with skill and experience its possible to overcome, but there should be something in place to keep the equipped playing with the equipped and vice versa but since rito cant effectively inspect each and everyone of our PCs before each game (especially with sandbox programs and what not to show only whats wanted to be seen) then the only things left to do are organize by area and assumed skill level, so we are seperated by area (NA east coast feels the neglect) and then by assumed skill level (which is ever changing)
