Do you find that interferes with toon space in your "my team" area?
I used to do something similar but now if I don't require some form of Nebu shards or the like from having opened the soul then they may as well stay unopened, I did manage to get Iron Eddie and Seventh Son Eddie within a day or two of one another about a fortnight ago but that is so rare for me, I just know the 700 odd souls I've saved for the sac event will give me bupkis...
