That might make her more balanced, but it doesn't make her more fun.
My problem with Gwen right now is that there's no flair.
I like playing high risk characters and I played Gwen for a while, but it just felt so bland. I ended up switching to Jaina because I felt there was more of a thought process involved in her gameplay. Like I get to choose how I want to be risky and had to think about what I was doing more. There's mind games to be played with Unstable Power, or what cards you choose to return, or when to ditch your embers.
With Gwen it's just like "should I dodge, throw, or attack? I have them all in my hand pretty much all the time." She really just plays Yomi in the most base form, which is fine but boring.
Gwen needs a trick beyond just drawing more cards.
