Why is no one using Poppy for this? On Twisted Treeline she can tank, and deal obscene amounts of damage.
The entire point of the build is she can tank and take a lot of hits due to armor and her passive. When the going gets tough, W>R>E>Q>Trinity Active>A>Hextech Active. This combo will approximately deal 1076.6 damage, not including Trinity Force's active and the damage from an autoattack. The burst potential is insane, and in a team fight you can even take out the other team's main damage dealer right away and slow all the other members, while taking no damage from the other two. The full sequence would be more than enough most times so you can save Hextech to take out a running enemy. With the slows, and the damage done, along with about five seconds left from your ult making you invincible to the rest, you can save the burst and carry your team.
That's my two cents, and I would love to know everyone else's thoughts.
