Riftwalk Nerf: Merely a Beginning?

Can everyone who is upset about the Riftwalk nerf on PBE calm down a little, please?

Riftwalk was always the problematic part in Kassadin's kit, as his overall nerf-resistance and continous ability to bounce back to permaban status have shown. So, finally, Riot decided to do something about it, and nerfed its range some (which they honestly should've done ages ago, when Flash range was nerfed itself).

However, that being said, this nerf should be merely the beginning - by taking power out from the ability that makes hims so obnoxious to balance, aren't they free to put that power back in somewhere else? For example in some base damages or AP ratios.
