You dont have to play her this way, its just a great basic way to get a high damage and still some defense, you need Banshee's veil if you are playing against warwick or other chasers that can stun you, cause if you gets stunned, your done. If you are playing againts champs like udyr and garen, that cant get to you in range, just get some more damage or a thornmail for their carry. You can also sell your boots and get another phantom dancer, if you think you need more crit chance. Thx for looking at my guide hope its helpfull.
