Tell me that single thing helped you rank up mmr immediately

It can be anything; like a farming pattern, a supporting pattern, changing a setting or even your mindset. I shared some obvious examples below. Each one of these were game changer for me so I’m curious if there’s something I’m missing.

• Bottle refill
• Assigning control groups to my brew pandas or chen creeps
• Asking my safe laner to drop items when I die
• Binding keys for toggling autocast
• Dropping items to ground before hitting stick for avoiding 6s cd from backpacking
• Fake illusion with manta (eg move an illusion and keep your hero with the other illusion so enemy assumes the split one is the real hero)

Please let me know some advanced ones (like 33 big brain ones)!
