Just Psylocke is much Superior than BP with mythic uniform, he does even have match with Psylocke when he is T3. BP pack will give you a few more rewards but you have to spend more crystals to get CTPs and that's it.On the other side Psylocke will give you unlimited access of her x-genes and MF,MC also. She melts WBU(who Doesn't have energy dmg reduction) , Her mind control helps on abx. She is totally worthy but if you ain't Interested then don't go for her, its a game, Nothing is must have here. If you asked then she is worthy or not , then I Think every player gonna say that she is worthy.
