How To Win Games From A Diamond Player With 18 Accounts In Diamond+

1. Play anything but top lane.
2. If you play top lane, play Ornn
3. Dont waste abilities on farming, use autos on farm then abilities on enemy. Alot of people dont rank up because of this. You run out of mana using your abilities on just farm, which costs you a lot more than you think. Some people dont even notice theyre doing it.
4. Dodge if you get either a Master Yi, Taliyah, or Lee Sin on your team. These 3 champs have way too high of a skill cap, and 90% of the time you will lose because of them. Unless theyre one tricks in that champ, AVOID them at all cost.
5. Get Objectives. You will rarely find people with 5 dragons losing a game.

Tldr;

Farm with aa, harass with abilities, dont play top lane, dodge games if you have a Lee/Taliyah/Yi on your team, get objectives.
