Consider when to cast Lunar Rush without Moonlight and when to wait for another Crescent Strike.
Landing Crescent Strike is critically important, but don't be afraid to miss. The cooldown is short and the mana cost is low.
Use Moonfall and Lunar Rush to stay on targets and activate Moonsilver Blade for extra damage.
Meditate is an effective method of healing damage over time, but Master Yi is susceptible to coordinated team ganks early in the game.
Although Master Yi cannot be slowed while using Highlander, other disables can stop him in his tracks.
If Master Yi tries to farm with Alpha Strike, hit him a few times so he has to use mana with Meditate to heal.

In either situation, try to do better than the numbers reported here to do well.
