I guess we will see.Will they require meter? Will they be safe? Will they loop? Will a character with great mobility have them? We do not know the specifics.
Batgirl would be balanced if she did not have the teleport. If she has safe 50/50 mix ups that loop, make these "fundamental Gods" close the gap in a traditional manner. I would bet any money they would never be able to get in.
They also cried for nerfs to Black Adam and Deathstroke allowing Martian Manhunter and Batgirl to dominate.
