Things you cant really do in low ELO and expect a win
Some of these can apply to more than just low ELO, but usually there is not the "but this is [insert low ELO rank], so it does not matter" bullshit excuse in those upper ELO games.
- Run a 3 tank 2 damage team vs a more balanced team
- Play 4-5 late game scaling champions
- Not ward
- Neglect objectives like Dragon, Rift, and eventually Baron and Elder
- Not gank any lanes, ever (afk farming your jungle basically)
- Die a lot (like 8+ times in under 30 minutes)
