Anivia changes?

So, iv been playing Anivia for a few years now, and now whenever I play her, I always seemed to get outclassed by the massive amount of mobility, now when i say out classed, i do not mean outright killed BUT lack of being able to secure kills or get out of a hairy situation. Most of every new champion that gets released now has some sort of gap closer/escape mechanic that is really hard to play around. I'm not saying change Anivias kit at all, but rather how about a movement speed buff? just a basic MS buff. Looking at other highly played mages (im looking at you leblanc, ahri ) they have great escape mechanics that are generally really easy to land/use effectively. In fact a lot of the mid lane matchups i usually end up playing (zed, yasuo, leb, fizz and ahri) all of them have ways to get around quickly. I guess my point it all i want is a movement speed buff for anivia. 350 ms with first tier boots is not good. especially against all these new mechanics. i know this game is all about changing and evolving gameplay, which i am a huge fan of, however i feel that if you are evolving the game in a certain direction with all these mobility champs coming out, i believe we should update the older champions as well to evolve with these mechanics, even if its just small updates that give a quality of life feel to them. because nothing is worse then the feel bads of dying under tower while farming to a champ that can get in to kill you and jump out before the tower hits them a 2nd time. Thanks for reading riot!
