I think it's about time we confirm the other change to Mega Man's Leaf Shield. Prior to this patch, when the shield was thrown, it would hit targets exactly once and keep moving past them. There was no re-hit rate or anything. Post-patch, the shield now has a rehit rate that's about the same as the rate that the shield hits people when it surrounds megaman. It's extremely likely that the thrown shield will double hit opponents as well when thrown accurately. Especially when the target is medium sized or larger.
This is the third buff to Mega Man's leaf shield, and only now does it sound like there's a reason to ever throw the thing as a projectile.
