Basically with the first 5 items you should be hitting for about 300ish magic damage per hit, with the added damage from poison and the burn from liandry's. With the hurricane your popping off 2 attacks per second dealing the same damage to each of 3 targets when attacking champions, minions or monsters. You're looking at about 700 magic damage divided among 3 targets. If that doesn't help win team fights idk what will, only problem is your a huge target and really easy to kill.
