Runaan's hurricane changes - WHY? ?

EDIT: Thanks FantasySniper for pointing out that the Runaan's change adds 10 damage to the main target compared to the old version, thereby justifying the price increase.

Original post for context: Runaan's is already considered a noob trap on anyone not named kalista or kayle (Maybe teemo? Twitch? ) So recurve bow was given 10ad and made 200g more expensive with a build path - GREAT. Runaan's had 10ad moved from the old passive to the new one - whatever. Nothing changes.

In balancing all of the build paths, every other item stayed at the same cost. Runaan's increases in price by 100g.

Let's put this in context: Blade of the Ruined King got the same build path buff, decreasing the combine cost and adding 10 on hit damage to the build, is already a wildly popular and good (debatably OP) item, and total cost stayed the same. Runaan's is a noob trap item that's rarely used, and it's cost is up 100g.

Where's the logic?
