if you're bronze you should stay in bronze. you're there for a reason (hint: not your team).
for everyone else, this boosting is fine, since there's no significant difference between silver and plat in my opinion.
i can say only one thing witch is opossite from yours opinion,
every player know to play league but you get better with playing with better players, you collect some tricks you see how they are cordinated (but again only if you are trying to be better) if you dont care you will just fall back to where you was
