How was Soraka's rework a success ?

I loved playing the old Soraka as a support, I didn't even play her as a solo laner. But everybody was crying for nerfs, and after few of them, she even got a rework. In that rework they clearly stated they don't want Soraka to just be a healer bot. I'm fine with the Q and E changes, it's a skillshot, not a "noob, point and click skill", my problem is with the W change. If you played the old Soraka, you know the frustration of playing the new Soraka and not being able to heal yourself when someone focuses you, Q heal is too slow or not noticable when you're being chased and focused by couple of people, even if you hit the Q, that is. Not to mention the health cost when you heal someone else, that's also just frustrating. However, lets get back to the first point of Riot not wanting Soraka to just be a healer bot. Instead of having 20+ secs cd on her old W, she now has a 2.5 sec cd on her heal, which makes her what ? A HEALER BOT. They wanted diversity, but what do you get when you have a 2 sec cd on heal, which also makes you loses health when being used ? A HEALER BOT. More so, I can only build resistance and items which don't give me health, otherwise my heal cost goes through the roof. Which in return makes you more squishy and again, "stay in the back - HEALER BOT". I'd wish they return the old W, but I guess she would just get spammed as a solo laner again, unless they make another changes, but I guess that's just too much to ask for.
