What are you guys aiming to achieve with these changes? As someone who was once upon a time a Sivir enjoyer, I feel like these changes don't really address the weaknesses of the champion. There are definitely some good ideas in here, such as the crit on R lowering cooldowns, but I feel like these changes don't address her on-going issues and why the lethality build is the more used build currently despite, in my opinion, being the worse build than crit. It's not because she doesn't scale off crit well enough, it's because she has issues consistently applying her damage with crit build due to her lack of range and requirement of needing more items than some of her counterparts, while also being a worse early game champion than most of the marksman who have similar range (Kog'Maw maybe being the exception, but I think he is more powerful than her early since his damage output is more consistent + he gets a bonus attack range on his main DPS spell).
