Doran shield start on adc's.
I just tried it on Draven i have to say even tho my support int'ed a bit cause it low elo it was really good vs their double ranged botlane of Vayne and Nami and since Draven is pretty decent at the start of the game the dmg was still there and the sustain was litterally immense.
Give it a go guys on stronger early game oriented adc's its rather fun.
