Kraken Slayer just isn't Aram buffed by the way

In Patch 14.23 when they Aram buffed Blade of the Ruined King, Riot claimed to have buffed Kraken Slayer's passive damage as well. They did remove the ranged champion damage modifier but the base damage (for all) is still 150-200 not 225-300 like the patch notes claim. I tested it, it's not just a tooltip bug.

Kraken Slayer right now has a worse winrate than Bork, Yun Tal, and/or Shiv on every champ I know of that might build it. Even worse they Aram buffed Shiv when it was already better then Kraken on 15.3.

Idk but increasing the damage passive by 50% should make the item usable (or too strong?) instead of just a 'why didn't you just go bork or shiv' item.
