I know it's been quite a while since the rework, but i honestly want people to look at this and understand why Sona players feel so cheated. Look at the changes in her damage, look at the changes in her ability to heal, heck look at how they managed to make her movement speed buff feel even more of a wasted skill. But most of all look at the changes to her mana costs and the how all her abilities had extra time thrown onto them. All this with out any real bonus for utilizing the way the kit now works.

I look at these changes and it's basically just one nerf after another. The only thing that i see as even remotely buff like is that her ultimate now costs less at higher levels. Since the rework she is now slower, all her spells are on longer cooldowns, her heal (and maybe all of the spells) costs more, her passive's damage output has been cut by 60% (assuming you are using her Q), she lost 650 range on her auras, her one attack spell has lower base damage.
