Next sivir nerf

I'll probably get negative comments on this one, but i just don't understand one thing. The next sivir nerf is going to be: Ricochet (W) total AD ratio lowered from 50/55/30/65/70% to 30/40/50/60/70% This will totally kill sivir. You literally lose 20% damage from w early game, and that's a skill you dont max until lategame. Right now it deals ~37 damage lvl 1, if the enemy buys a dorans shield, chances are you'll even heal them more. You'll literally lose 2 levels on w, since you get back the old damage when the skill is lvl3. You'll deal like, 20 damage to the enemy using 75 mana next patch... Shouldn't riot just nerf something else on her, like anything else, for example spellshield? I'm sure the w was never the main problem for the players to play against, maybe lategame, but its changed early game.

Instead of totally killing this champion, cannot we put a little buff to the weaker adcs? Sivir isn't even that often picked lately, on the other hand top tier adcs started to spam jinx.
