I haven't played Ranked in a long time, but regardless I guess I will toss in my two cents.
The "mentality" you are looking for isn't determined by whatever bracket you are currently in. It never has, as your ranking isn't based on what you say or do - it's based on how you play and whether or not you win enough to get promoted.
From what I can tell of your two threads you've made (referencing the other one requesting Lytes attention) you are more so looking for higher tier players to play with rather than looking for a person in general who you can befriend and they can help you. Just because they are a higher rank than you does not mean that you will fit in with them - or that they will help you dampen your toxicity issues in regards to "low caliber players" as you have put it.
Attitude is determined by the person alone, not their skill level. In all honesty it's not hard to make friends on League. If you enjoy a game with them add them to your friends list and play more often with them. Eventually you could end up great pals. I know back in 2010 I met someone during a random normal game and I've talked to him almost every day since then. Granted you may see someone play a terrible match, but that does not mean tear into them with every vulgarity you can think of. You could help them by giving advice in a calm manner. If they don't want to take it, just leave it be and you can ignore them after the match so you don't have to play with them again. Heck, you can even mute them during the game. There's no reason to fan any flames whatsoever, as it usually only results in your current predicament - suspension.
In short, you can't expect a "better mentality" only from higher tier players. There are thousands of people who have a non-toxic / helpful mentality that are well below those ranks, assuming they even play ranked.
Hope this helped in some way.
