In the future you can get GNW Neji in shop, so yeah, it's not that hard, you still can have a 3 star one and it's not bad at all to sue a 3 star while waiting for the shop updates . GNW Neji's Mys also boost the evasion rate and cause high combo, so yeah, they have to make sure that the skills are balanced. Also, GNW version is usually better than the original one, like GNW Neji has a chase that causes Acu. I still would recommend using GNW Neji or GNW Ninjas in general
