I can understand why fans are upset and honestly it would have been better if Levitz just left it alone but, seriously, it's not like Bertinelli was going to show back up regardless.
Also, a Helena Bertinelli died. There is no indication that she was ever Huntress (most likely she wasn't). Really, this is more of an homage to Bertinelli, "Damn shame to waste an interesting life." It's right there and it is a damn shame.
