She is kinda old but still very good but there are a few quality of life changes that I would like. I just recently started playing her and learning her is hard because of the following reasons.
Change 1 would be a nice QOL change for when Annivia is using wall to troll her own teammates.
Change 2 would make the bird OP as hell, being able to dive her and CC her to cancel Ult channel is part of the counterplay to such a strong zone control mage. Annivia already has good teamfight potential, this would make her absolutely broken in teamfights b/c she can just drop her R in the middle and not even have to worry about being CC'd Bonus points if her egg is not on cooldown.
She needs some help but I don't like your ideas. I think she needs lower mana costs and faster Q speed. Stronger armor on egg would also be nice.
Those aren't QOL. Those are huge buffs.
Either one would break anivia.
QOL buffs are super small buffs that make a champ feel better to play. Like adding indicators to abilities or smoothing animations.
Can allies please just be able to walk through the wall xD, or be able to cancel it early.
Nah, that would be too easy. Let those Jarvan and Yorick players do their braindead terrain spells without thinking about how it can hurt their team (to be honest, yorick's W being impassable for both teams would be really stupid because he and his walkers are melee, it will be really hard to use this well, and jarvan needs his ability to cancel the crater because his R is part of his core combo and he can't just "nah, that crater will kill my team, i won't use it")
I wish her ult would stay on and act like dongers turrets, you can hourglass, and back with ult on so why does it have a channel?
Because its a literal death zone once its charged. Minions cant pass through, champions that enter will take 1k+ E, quite huge ult damage and a slow that makes hitting Q or blocking the way out with W easier, and there is no way to wait this out or somehow outplay this(like you can with heimer's turrets by dodging their laser). The only way to counter it is to cc anivia or force her away and use the cd to do things
