Just curious if she plays any other roll than buff and push. Also what are must have items on sivir

not really, though honestly, she's good enough at what she does to not need any more roles...

I still think aura Sivir rapes, I have no idea why people stopped playing her. I imagine the inevitable Ezreal nerfs will increase the amount she is picked.

In the kitchen.

I don't really get why Ez being nerfed would affect Sivir in any way. They have two fundamentally different roles.

While you can harass with Sivir, her strongest point is easy lane pushing.

Ez is a poke/ganker with very w/e early to mid(unless you use ult exclusively for it...) lane pushing.

Ez being nerfed would probably see more Trists then anything.

On sivir i do the following items:
Vampire talisman (later starks)
Berserker boots
Frozen mallet
Starks Fervor
Bloodthirster
Infinity Edge
Phantom

Really owns.

If her ricochet procs on hits wouldn't a tiamat ( i know their awful) make her slaughter creep waves faster? or by the time you spend 2k is she already able to 1-2 shot creep waves anyways? (very limited experiance with or against her)

Her true steroid is Ricochet. Because of her range, you generally have to swing at the tank, which is fine. Because you have Ricochet. Ricochet doesn't apply on-hits. It doesn't crit, apply slows, or respond to life steal. Ricochet grows one of 3 ways: +damage, +attack speed, and armor penetration.

Because of this, the most awesomest items to get are Brutalizer, Stark's Fervor, and Youmuu's Ghostblade. For late game you'll probably want a Bloodthirster (possibly replacing the Brutalizer) and a Guardian Angel which every carry should have at some point in the game. Also have Elixirs. Elixirs are awesome and Sivir can easily farm them.

Running around dealing damage as though your opponents all have 90 less armor than they do... That's going to work.

Also, with your ultimate and Rally... Well that's just going to hurt a lot. Even if you get chased down and have to get out of the battle (which you can easily do with E and R) your team still has improved Rally and the buff from your ultimate.
