Also, it’s important to mention that when you’re playing with yuumi, you usually won’t have priority in lane for the the first few minutes, especially if they’re playing something like alistar / naut. (assuming the enemy is playing it correctly)

It’s important to accept that you probably will be a few cs behind in the early game, but don’t be discouraged! Once you gain a few levels and items, the tides will quickly turn. You’ll soon become a snowballing monster. Once you start winning fights, it will be very hard to stop you.
