How can you say that she is just "angry amazon with a sarcastic streak" when we literally saw a different side of her in this issue?
Artemis is a character who hardly appeared since the 90's and Lobdell has to build her from zero. It’s takes time and so far he is doing a great job with her.
And from where did you got that Jason has a crush on her? Because I'm completely sure that he isn't romantically interested in her. Lobdell even implied from the beginning that the two will have a platonic relationship.
Also, I already said that Alika is just a plot device. I just don't think that she is a "shallow" character because we know that she never wanted to be a shim'tar and something bad happened to her when she got chosen. We also know that the Bow affected her and made her go crazy. That doesn't make her just an "evil" character.
