Fellow MF, players...
I generally start with Doran's Blade, a health pot, and a ward trinket. With the Doran's change, I'm considering going with a Long Sword, two health pots, a mana pot, and the trinket. Reason being that I get to the BT faster, and I can harass with her W way more early, hopefully screwing up their CS or even forcing them out of lane to back early. It also would help ensure that my mana is available for her ult when I hit level 6 without having to pass on good poke opportunities with her W.
I dunno, it might be worth trying for a match to see if you can get ahead a little faster, though it's a slightly riskier start.
keep starting dorans
80 hp too good to pass
