Use Double tap to control your lane. This is why we pick up the long sword first, the extra 10ad help. Kill some minions, and pick up the Amplify Tome and your Boots of Speed. With the extra boost form your Tome will make your Make it rain spell a better set up for your Double Tap, and the boots can help you chase down your opp. Save up and farm, try to get a kill or two, but don't over commit. Once you have enough, pick up the Revolver and the B.F. sword. Kill and farm. Take any opportunity to help out your team in team fights, and push lanes. Once you get your Gunblade use it's active to finish off you opp, and once you pick up the Deathfire Grasp make sure you use it's active at the beginning of your fights, you'll be able to set them up and knock them down. By this time your
Make it rain will be dishing out around 700 damage
The passive from your impure shots+regular attack will be around 450-500
Double tap, which will hit for about 650 damage
Bullet Time will be hitting them around 1000 damage (if you catch them in it the whole time)
This is a blance build, let me know what you think.
