The thing about the sleep attack is - your main needs to be the last one to attack in that lane, and if your main is facing an empty lane then it's in most cases useless. I gave it a try for a while, but went back to the standard tai attack as the ignite chance is too good =)

Think of it this way bois and gals - it's a trade off for not being able to start a combo with your standard attack. If sleep is so crazy strong why have I not been seeing tayuyas everywhere... Sleep is kind of RNG based too, by which i mean it's based entirely on your opponents lineup and positioning - unless of course you don't mind having your main as Move 4 - which I don't really ever recommend as Blaze.
