seriously man? okay lets say i take you seriously and assume you are not mentally disatvantaged:
"With a 51% win rate you pretty much will never advance in a division because to win promos you need to have a 75% win rate for normal promos (1 win to get into promos plus 2 out of 3 in promos) or a 66% win rate to go up a division (1 win to get into promos plus 3 out of 5 in promos.)"
this is what you said right. its like so stupid and bad i dont even know how to properly reply to that. its like you are assuming that a 51% winrate means you win one game and then lose one game. it doesnt mean anything except that overall you win 51% of your games. you can still have 20 game win/lossstreaks and climb/drop easily. i mean look at your account, you have 48% winrate overall but still 78% winrate over the last 9 games and you probably climbed/got boosted to silver 5 with that.
like oh my god how can you even say something like "to win promso you need a 75% winrate" xD
okay lets get to the next part:
"The changes to the system will do absolutely nothing to help people climb within a division, they simply lower the win rate required to succeed at a promotional series to something more manageable so someone with a 51% win rate doesn't have to do 10+ promos to advance."
ofcourse it doesnt give free LP within a division but since a player who is 50 lp in silver 5 doesnt ALWAYS have 50lp in silver 5 but only has that ON AVERAGE also gets into promos sometimes and also falls to 0 lp sometimes, he statistically gets a free win every so many games. this has less effect on some people more on others but it DOES effectively give free wins and thus changes peoples winrates and their effective elo.
"Your logic is flawed that these are "free wins" because promo helper doesn't give you any LP. Like I've said earlier, all this does is decrease the number of promos you have to play in order to advance and softens getting demoted right after you get promoted because of a couple bad games (one troll/afk shouldn't be able to negate all your hard work of winning a promo.) It doesn't help you at all to climb from 0 LP to 100 LP within your new division."
getting demoted because of trolls right after winning promos happens as often as you get promoted because the enemy team had trolls and sucked. you statistically win and lose the same amount of games for free and if you keep dropping, that is simply because you dont belong where you are. if someone hangs between promos and demotions, he is simply at the verge of these two divisions, skill wise. hes better than bronze 1 but not quite silver 5 yet so he climbs/drops but now he will climb more easily and thus get an "elo boost" into a division he doesnt deserve yet. statistically, he will climb/drop sometimes and he will get free wins sometimes and this will influence his overall elo because mathematical facts.
"Overall, this system will allow people who are below the rank that they should be in the ability to rise to the rank they should be in fewer games and will reduce the power that trolls/afks have in promo games. However, this new system will be of no use to people who are at the right rank because it won't help them rise within a given division (i.e. going from 0 LP to 100 LP.)"
nobody is below the rank they deserve. everyone is exactly where he has to be with maybe one division variance so if you are silver 5, you might aswell be silver 4 skill and you will get there with enough games automatically because thats the level you play on. trolls/afks dont have any influence on promos anyways because as i said, statistically you win the same amount of games from them as you lose and "promos" are no special kind of game, they are an illusion. you coulda just lost 3 games because of trolls and it woulda ended in the same way but noobs think "OH NO MY PROMOS OMG" because they dont understand the system. they think "omg i need 75% winrate to climb omg" but they dont realize that sometimes they are at 0 LP and they dont drop after losing a game or they are at 2 lp and only drop to 0 instead of -20. they dont realize that this system equalizes itself and there is absolutely no luck involved in where you are in the ranks.
you know, thats why its so hard to talk to noobs about anything. they just dont understand. its like discussing quantum physics with a third grader.
