What's the context of the Morg nerfs?

I'm aware that Riot is attempting to keep support Morg fine while trying to not touch her mid too much, except this nerf does exactly that.

Tormented Soil (W) damage changed to [16/32/48/64/80 to 24/46/72/96/120] from [24/38/52/66/80 to 36/57/78/99/120]

This is, honestly, an unacceptable way to nerf Morgana and all it does is push Morg back into support. She's not even seeing as much play lately and NOW they're nerfing her. W is mid's spell. It's the thing that mid Morg lives and dies on. If you nerf her W you have to max it out to even waveclear effectively instead of leaving it at like 3 points and maxing Q.

Mid Morg has always been known for her safety and waveclear, even if by today's standards her clear is kind of mediocre. Cutting her W damage by this amount early game is going to make mid Morg even easier to shove under tower while doing little to deter people from playing support morg. She'll still sit bottom and fish with 3 second snare Qs into ult and the minor amount of damage off her rank 1 W (Since you max Q in lane obviously for more CC duration) isn't going to make or break engagements bot. If her lane can't kill a snared target in the time they're CC'd then the 3-4 ticks of 24-36 damage isn't going to get the kill.

Think for once, if you want to get her out of support but keep her mid utility then start speeding up her kit. Make Q snare less but R stuns sooner and her W ticks faster. If you want her in bot forever then just say so, don't try to play the 'she's like Lux, can go bot or mid' card when you're nerfing her ability to go mid while not touching bot.
