Hello guys ! Master's W is already to old and useless beaucase if you are level 11 and above you kind of forget it (the spell) and il be great if could help in team fight by that i mean instead of sitting and healing to creata a green shield on him like the blood sword and heal him ( or not) with that you could help your team better. Please Riot!

Or you can learn how to time Meditate in the middle of a fight, because it's actually really useful when you know what you're doing.
Think about it for a moment. Master Yi is a high-priority target, because he's squishy and deals a lot of damage. If you can time Meditate when their CC is on cooldown, you can sustain through much more damage than you could normally handle, while also giving anyone on your team an extra 4 seconds to set up easy kills for you.
