Vanishing in Brush While In Combat
If someone is in combat when they enter a brush, they should remain visible for at least 0.75 - 1 second. One of the single most frustrating things in LoL is when you're fighting someone or about to kill them, but your auto-attack/spell auto-cancels mid attack/cast because you lost vision. Brush should never cause an auto-win in a fight or a perfect escape route. If you attack from a brush, your stealth cancels because you entered combat, so why should you be able to instantly vanish when entering a bush while in combat? 0.75 - 1 second continued vision is not to much to ask for when an in-combat player enters a brush. It could even be limited to in-combat vs champions that way minions don't perma-follow.
