One bit I really liked in the finale is when Wanda learns to teleport, even before she's come into her full power as the Scarlet Witch, just by imitating what she saw Agatha do (and even making a gesture like Agatha to show where she learned it). I did like that they showed she's not just someone with a lot of power, she's also a fast learner.
It's funny that for most of her comics history Wanda couldn't teleport at all, or only under very unusual circumstances like being hopped up on DC Universe Chaos Magic. As recently as "Children's Crusade" I didn't know if she could teleport under her own power or just the so-called "Life Force" power, but now it's pretty clear that she's a teleporter and always will be.
It reminds me of how in "The Yesterday Quest" they made a whole point of how she couldn't magically change into her Scarlet Witch costume. And I don't think we ever saw her do it through most of her comics history. Even after they made her more powerful she had a very limited power set, like in the 1998 run that showed her falling to the ground after levitating herself a few feet off it.
I worry when she gets too powerful but I do like her having more tools at her disposal and would like to see her in an Avengers run where she gets to use the abilities she didn't have in most of her Avengers history, like flying, teleporting, transmuting, costume changes, etc.
