This build has a lot of potential, especially against squishie champions, you can stick to people very easily (frozen mallet) and you are quite tanky while putting the damage of an ADC.
the way you play early game is being safe, quick trades, then recover you HP with W to go back in for another trade, in team fights,wait for you team to suck up all the cc, then you Q/flash straight into their adc or apc, if you get cc on, you are pretty much ****d.
