instead of nerfing champions when they become strong in low mmr
maybe riot should make detailed videos and short strategy guides for every champion to be accessable in client to explain their mechanical and strategic counterplay.
similar to champion spotlights with gameplay segments that teach you how to play a certain champion, maybe there should be similar guides what to do when faced with them on the enemy team.
there could also be a more extensive tutorial that explains beginners basic lane mechanics like damage checks without overcommitting to fights, and how to keep your focus on objectives and close out games when youre given the opportunity.
one of the most common questions you can see on the boards here is, "how is champion x balanced" or "how do i deal with champion x".
there are a number of third party sites that offer player written strategy guides, but little by riots own sources that are easily and obviously accesable for inexperienced people who dont know where to look yet.
. Ill ask again though, where's the carrying myself out of bronze with champions that have a learning curve?

? The argument I'm even trying to make is that low brain champions stomp high learning curve ones without a team.
and similar champions will always be trash in low mmr, simply because they are harder to pick up than other champions.
