@Gypsylord Experimental Sona Changes
I read up the changes you are trying with Sona on the PBE, and while I like the selfish MS buff on her E and stronger shield for late game, as well as her CD reduction for her Q, I don't feel as though those buffs constitute lowering her aura radius's lower than they are now. She already has to get dangerously close in fights to tag all the right allies, but now it will be certain death. I understand what you are trying to accomplish, but I would rather Sona regain some of her more mage-like qualities instead.
For example: I would love to see buffed damage on her Q again and sure you can nerf her Staccato if need be, and if it takes making her Q a skillshot on an ammo system to make it so she can have damage again, then I say do it.
The way I see Sona is a scary AP support who CAN defend/help allies but more so use her music to make her enemies feel fear when coming to her allies (Q). That's what I feel would be better changes.
