When talking about the Mel nerfs, Riot stated,

“Mel’s changes this patch are aimed a bit at reducing frustration – eg. The lingering of her E zone and the particle are slightly mismatched (this follows the behavior of several other similar types of spells), but is resulting in a little more frustration than we think is worth it. E max is also being reduced in power level and being a little more costly for her to cast.”
