Batgirl is enticing, in a number of ways.
Another victim of the debilitating Character Crisis contagion, my list is longer than the most sesquipedalian word.
I LOVE Batman as well, but have been hesitant to use him due to the nigh-exhausting numbers of Batman clones online, etc.
I like Lobo as a character and still use him frequently despite his proclaimed "low-tier" status, yet he is more of a side project at this moment.
I began maining The Joker and KF. Dropped KF due to redundant combos. Still "Love That Joker"
Raven, GL, Hawkgirl, and Aquaman (It's a Piscean thing) have been in my roster. And now I must add Batgirl.
Way too much fun to use. Always loved the character ever since Yvonne Craig epitomized her persona. The Adam Hughes art for her and WW are superb! (Recently considered adding Linda Carter's alter-ego to my list as well)
Perhaps I should start a Character Crisis support group
