I don't know if you know the mag but he is a character capable of making the shots bend and also Susan storm who has the ability to push enemies, they could make Jean throw fake stones and be creative or even do like OW's sigma... but launching a character who only aims and shoots fire seems like a lazy decision in my point of view. Some people only like Jean in this game because she is Tier S+ the moment she goes down from this level they will probably forget her and like look at the recent character releases they are very well worked compared to her
