Riot intention to lowering his skill floor and making his gameplay overall more rewarding is more than welcome.
Aurelion Sol has been in a weird place balancewise, because the meta didn't favor his counters and because of his really high skill floor (aka the minimum level of skill required to make him work consinstently) made him seem worthless in the hands of ppl who didn't have lots of games with him while also being incredibly strong when played by dedicated players (there was a spike of 7-8% in winrate).
That said, I'm welcoming changes that reward more his plays because right now you need to continously keep a high level of playing in order to deliver some impact on the game.
Back to Annie, her AA range lets her farm from a rather safe distance and I've faced a lot of Annies able to hold back and being even ungankable while stacking their stun, if she over exposes then it's right for her to be in peril. I brought up Aurelion Sol because he has the same exact weakness (can't get out of ganks/dives) but for some reason he is dead when some1 gets the upper hand while Annie can litteraly instakill you and the ganker while getting out with more than 50% of her HP.
