Great build. Won many many games with it already not had any problems with lack of damage or farming. At level 2 you should play fairly aggressive throw your flag down pull to them knock them up get a couple hit's in and back off rinse repeat until they die(very easy to get first blood with ignite). Usually around level 9 you should have your recurve bow+madred's razor you will fairly easily be able to kill dragon by yourself provided there is no enemy champions around(and how many procs you get from madreds >.<) still should not be a problem. usually I'll advance the lane then when Fog of war is over me I'll flag and pull through the wall. Other than that the build is pretty simple. Frozen mallet assures they will not get away also frozen mallet with health per level yellows, and flat HP quints provide a fairly decent amount of hp for your atma's bonus to be effective. On the rare case that the game would even continue long enough you can get w/e kind of defense item you need. Banshees is my personal choice in that field but you could get whatever you prefer or whatever is more beneficial in your current match. Well try it out you will not be Displeased as I know I have not been :D!!
