Playing against Master Yi

How to counter and exploit weaknesses

1

Hard CC (stun, knockup, suppress) is the only way to stop Master Yi — save a CC to shut him down.

2

Master Yi is very weak in early game jungle: invade him and contest his camps early.

3

Don't run away alone: Yi with R is faster than you and immune to slows. Group up instead.

4

Point-and-click CC is the best counter because he can't dodge it with Q if it's instant.
