How are you playing him now. are you using electrocute and building ap and playing assassin.
or are you just taking a standard adc rune and playing safe while farming creeps with tear.
I was thinking he would be pretty good with conquerer + triforce with the new pres of mind giving 500 mana after 5 assists/kills, maybe even with pres of mind + manaflow band. and if conquerer is adaptive stats maybe even conq ap ez with gunblade + conq heal + 5 stacks of rav hunter for meme healing.
