Akali is a very skillful champion. No matter the players crying over how much damage she deals (even though they consent with champs such as Talon and Zed), you'll need the proper mind and fingers to land her skills to give the biggest damage output, as well as to position properly when team fighting, roaming, or taking objectives. Even though she can snowball very hard, late-game can give a hard time to any Akali players. So, try to knock out enemy players as much as possible, to always get the upper hand during the game, for a fast and easy win. Use the practice tool as often as possible, as well. You'll definitely need it.
