I will actually add that in as a second build idea, I just realized I do that in some games, depending on the lane. Thanks for the idea bdombe1, i will credit you :D

Thanks for the curiosity... I like to go 3rd point in twirling silver because I find it to be more helpful with less CP, Achilles Shot does almost nothing until after first back, so the Twirling Silver point gives the AA speed steroid and the movement steroid AND the damage increase. I can see running with Achilles Shot 3rd in an aggressive lane, but I generally try to play more passive early so as to farm and not die. Also, if you do farming right you will have a crit on almost every AA, you get in a nice cycle of finishing every minion with a crit, Extra AA speed = more farm for me. I can totally understand running Achilles Shot though :) I guess what it all boils down to is that the most important thing with this build is gold advantage. And Twirling Silver gives that to me, but if you are better at farming with Achilles Shot, by all means, go ahead.
