User blog comment:TheTobarMethod/So...Tri-Force Vayne lol?/@comment-84.183.47.247-20130303014540

Vayne is arguably one of the weakest AD carries early and late-game. In exchange for this weakness she snowbawls extremelly hard if she gets a few kills early or mid-game.

Triforce is an midgame item that gives a lot of stats for champions that can use them well: offensive, defensive and utility.

Vayne however is a champion that depends on her snowballing (offense) and already brings massive amounts of utility. Even with her Q triggering TF all the time IE and BT will still give more offensive power. With her passive and her knockback she doesn't need the slow trinity provides to escape from or catch up to people (same goes for the movement speed). The AP is entirely wasted. It doesn't give you the stats you mainly want for its price (still the most expensive item?).

I like Trinity Force and I like the idea, but I honestly don't think its a good item on Vayne. As a matter of fact, now that static shiv exists I don't think it is a good item on any AD carry.

Just my 2 cents.
