On Anivia "Bugfixes" and Patch Note Transparency
In the patch notes for 7.14, Anivia recieved two changes: A "bugfix" that made cc effects properly cancel her ult, and a change to her wall to no longer give it the ability to grant vision. There's two big issues here:
First, this needs a lot more transparency. The loss of vision on W is a huge nerf - I don't think riot gave enough credit to exactly how big of a nerf it is. As a control-oriented mage, vision is an important thing to have, and in fact many of the use cases of the wall revolve around that vision. Checking jungle camps, getting a quick pick on a fleeing enemy with the E, etc. Easily 50% of the use cases of wall revolve around the vision. This change is a massive nerf, and comes with an added detriment - while I haven't had time to properly test this, the wall should now actually BLOCK your vision, making it even more detrimental to use improperly and creating even more trouble for allies. This alone should have given Anivia her own place in the patch notes, along with Ivern and Trundle, instead of a small footnote that won't be read by many players. (Ivern's cast range got a huge nerf - that should warrant it's own section in the patch notes as well at the very least)
Second, the "Bugfix" is, well...only partially a bugfix. It states that fears, flee, charms, taunts, and knockbacks now properly cancel her R. But ehre's the thing: Fears, charms and Taunts are now IMPROPERLY cancelling her R. While the changes to knockbacks was actually a bugfix, it has been stated before by Riot themselves that the R is intended not to be canceled by Fear, Charm, or Taunt. Many matchups for Anivia revolve specifically AROUND that interaction, which has been there since practically the start of the game - Anivia players KNOW they can cast their R without worrying about Ahri charm, etc. This is a flat nerf, not a bugfix.
Anivia should have had her own slot in the patch notes for these at the very least, and while I don't know for sure about the actual balance impact of the nerfs, I believe them to be far too strong, despite her high winrate right now.
Edit: Tested and the Wall doesn't block allied vision. All other points still stand
lowest HP, slowest MS(except unmounted Kled). No escape. now has no vision on the wall which can help the check bushes without having to wall all the way near it to place a ward. take the wall vision away, thats ok but at least give her more Hp and MS.
