Just so not everybody leaps on me, here, I’ve just spent half an hour reading and have also scanned all the questions in the FAQ (Hero Costume/s FAQs! Please read for answers to most questions before posting new questions).
I don’t have time for more reading. (PhD in Costumes, anyone?)
Seems to be related to FAQ #6:
What to do if you receive a hero and costume you don’t want?
I already have Bane fully maxed with a costume fully maxed, and I now have another one. I don’t seem to be able to feed the costume to anybody else, and I don’t think it’s worth maxing another Bane and costume only to feed him to someone else (please let me know if you’ve done this and think it is actually worth it; I haven’t been impressed with the number of points I get for using an unlevelled or partially-levelled hero to level another).
Are there options?
Thanks for any help, for me and others with the same question!
