imo:

BotRK is an overpowering item for AD Carries since it gives them free peel for themselves, a giant, low cooldown, nuke, and insane on-hit, and, most importantly a ton of lifesteal. Vayne is especially bad because it just fits so perfectly in her kit. Vayne with BotRK, BT, and IE is nearly unkillable becaus of how much she heals per auto combined with stealth, condemn, and tumble's movement. I won't go into how it works really well for Varus and Twitch too, but let it suffice to say it does. Riot should, again I stress my opinion here, remove BotRK as it makes AD Carries to powerful at all stages of the game as opposed to the late game where they're supposed to be strong.
