The specialists were released some time ago. Not many used NX.

Over the year(s)[idk] people have gradually adapted to Nexon's P2W style, and now many people like NX.

The craze over Mutagens wasn't as high when it was released because the NX population had grown larger.

Also, it's only gamemode specific. Specialists can be used in any game mode, making it seem universally OP to the community.
