Which sucks because yet again DC treats Batgirl fans horribly. But yeah Beechen did so much damage to the character it isn't funny. First he make's her evil. Then he continues to make her evil even after she was off the drug and acted like nothing happened. Then instead of a seperate story we get six issues of Beechen cleaning up the plot holes of his Robin arc.
Why couldn't DC just give the story of Cass's redemption to Chuck Dixon as it originally was to be. You didn't know that right? That Dixon was to write a fill-in issue of Tec involving Cass? It was on Newsarama in a podcast interview involving him before the big fight he had with DC and left.
