Sets of Nerfs to Sivir and Taliyah on the PBE

> Sivir > * Base mana regen reduced to .8 from 1.6024 > * Base AD lowered to 54 from 57.46 > * Spell Shield (E) cooldown increased to 22/21/20/19/18 from 22/19/16/13/10

That reduced mana regen will seriously damage her early game harass and waveclear, which would make sense if they wanted to solidify her as a lategame carry (thus weak laning), but the increase to her spell shield cooldown (especially at later ranks) will hurt her late game far more than her early game. Both nerfs are also massive enough that it could be difficult to tell which nerf isn't pushing her in the direction they want.

> Taliyah > * Mana growth lowered to 50 from 60 > * Base Mana regen lowered to 1.2 from 1.4 > * Mana regen growth lowered to .16 from .17 > * Threaded Volley (Q) no longer deals 50% extra damage to minions. > * Unraveled Earth (E) trap damage lowered to 80/100/120/140/160 from 80/105/130/155/180

Taliyah's nerfs are also fairly immense. Primarily, the complete removal of the bonus damage to minions with her Q. While her ability to clear waves won't be completely destroyed (she can always use her E and W as well) that will cost far more mana and put her in an incredibly vulnerable position. This will have a dramatic impact on her throughout the entirety of the game. I could understand reducing it from a 50% bonus to 25% or changing the % bonus to increase with rank, but to remove it completely feels quite drastic to me.

I personally consider these nerfs to be rather hard on these champions, though I do believe some nerfs to be necessary.
