A lot of you have been asking about trench warfare, how to get out of your trench. Here you go:
1) You need 10,000 behaviour or you are not going anywhere.
The higher your MMR the less this matters, 7k+ doesn't matter, 5k+ matters less.
But for everyone under 4k this score matters more than your last hitting.
You want team mates who can carry you? Make space for you? Save you? You need 10k behaviour baby cakes.
2) Use your forced support role queue games wisely.
To raise MMR you should specialize in mid, carry or offlane. Mid will get you out of trench (or keep you in your MMR skill range), carry same, offlane less so but still impactful.
When you win 10 games in a rows the coordinator will soon test to see if you are a smurf, it will give you the worse team possible, people known to be feeders, or toxic or both. Once you get those bad games switch to building up your role queue games playing forced support. You will be losing those games regardless so make the most of it.
