Fixing Sona.

Remove the scaling on her heal all together, and make it a crappy percent, then give the shield component higher base, and more scaling so it doesn't seem like a shitty afterthought.

Make her Q only hit one target enemy champion max, (can still hit 1 minion or 2) but increase the scaling and base slightly, and increase the team buff aura's power scaling also.

Her aura's need to feel like they are doing something, and as it stands she brings NOTHING interesting to the table. One of the lowest damages for a support in the whole game. Ask yourself "Why would I pick Sona over Nami?"

E is fine, R is fine.

DONE.
