I would vote if this was a 5v5 build. I think that with better players on both teams you cant use MF well, as she is very reliable on enemy focus and even in 5v5 on ranked games etc its super-hard to run away

Thanks Saelak,
Thanks Hawk, I did play a lot of games with an early BT, I don't feel the lifesteal helps much since she dies to fast to make much use of it, however I did like the passive AD gains. Trinity Force is awesome for obvious reasons, plus it's a nice way to add more crit% to take full advantage of Infinity Edge.

My main is MF, interesting build. Early domination is definently key. Thats why I always roll with double up fast and upgrade it fast. I also but vampiric scepter first then build my b f sword. This is very early attack damage and you hit like a truck, and along the way gives you bloodthirster. I did take one thing from your build though, the Trinity Force, and damn good call i might add. Good build

I tried this build out and it makes for a very powerful MF early game that carries herself through endgame as a powerhouse. Awesome build.
