really depends on what your 6* roster looks like...features cost 5k shards more and a high chance to get basic champs and not the new ones...if your roster is deep...meaning 35 - 40 or more 6s with a good number of them duped, I would risk on a Feature, otherwise I would rather save the extra 5k shards and just load up on new or dupes.RNG plays a huge role in Feature
