Kindred bug with Hail of Blades.
After a bit of testing around with Hail of Blades on Kindred, I went into Practice Tool to help me get an idea about how fast I attack during which level etc. etc., and I happened to stumble upon a bug regarding Mounting Dread. When you engage with Hail of Blades ready, Lamb won't do the animation towards slinging Wolf at the target, but it'll still do the damage. And after engaging again, Lamb will sling Wolf even when the mark isn't ready to let Wolf do so. From the quick glimpses that I get between each auto, it seems to do the amplified damage that you'd get from the third stack on E, both when there is no animation when there should be, and when there is an animation when there shouldn't. Keep in mind, this is with a build of Warrior Enchantment, Stormrazor, Rapid Firecannon, Runaan's Hurricane, Blade of the Ruined King, and Berserker's Greaves. It may not be a consistent bug to make Kindred unplayable, or unfair, but that doesn't excuse letting this go on if Kindred does happen to get an attack speed oriented build up and running. This bug seems to happen around 2.0 attack speed. With the build I stated above, the base is 2.03 without Q attack speed steroid nor Hail of Blades', 2.81 with just Hail of Blades, and with both Q and HoB, the keystone stops working altogether, thus letting Wolf work normally due to the rules of the keystone forbidding more than 1.5s between each auto attack. With the image provided, you can see that Wolf is being tossed even with the E mark not fully colored in.
