Build blood thirsters had three last game ended game with 281 cs and 512 ad.

But then you wouldn't be able to have either Mercurial, Last Whisper, and IE/Trinity. Not worth it IMO, as those would make him do more damage through his autos than 3 BTs would.
If you're playing Talon/Riven/Kha/Mantheon though, go for it, BT stacking on AD casters/assassins is amazing.

i had last whisper and sheen as well as the berserker greives

almost had trinity but we ended it before i could back
ended with 16k gold

dont build trin force on ezreal now, icebourne gauntlet does its job much better

don't need anything but bloodthirsters
