I'd like to change your view about the term "elo hell"
Elo hell is not where your team is holding you back, its where you can't find a way to carry. Unless you're a support main you are in fact a carry and have the job of carrying the team to victory. So if you're losing games where you're even or below even then that game is deserved, if you're losing games where you're 19/1 and everyone on your is 0/20 then you were trolled. Here's the main point if you go even or just a bit over or under, thats okay. It just means you have work to do and thats great, everyone has to work on something.
Note All my opinion below
What elo hell actually means
The place where you are no longer able to carry, and can see no other reason for the loss other than your team mates.
Why is this elo hell more accurate?(my opinion ofc)
Because with this mindset you set yourself on a pinnacle and everything around you is holding you back from achieving higher.
Just my 2 cents, ofc
Elo hell exists everywhere its not limited to bronze/silver.
It is where you hit a wall where your skill is no longer enough to push you higher.
It is hell because you have to rely on people, and once you start doing that you see every error they make as a reason they're holding you back.
Long end of it all, if you want to climb you have to carry
If you're not carrying you're being carried
Everyone gets carried occassionally
