I just pulled my first Elektra from a heroic token. I don't have enough HP to add her to my roster and I don't want to buy any more right now. Is it worth dropping a maxed 2 star wolverine or thor to add her? I've basically finished the 3 star transition so I don't use them that often but I'm concerned that they could still be useful for the heroic pve's.

Thanks.
