I know not many people like it but I want to share my 'personal' thoughts on these two legendary secondary in which one is free and the other is behind a huge pay wall.
I don't like these cool fancy stuff in a shooting game apart from mythic and other legendary guns skins they would be somehow good in order to contribute to game to be alive. But there are many other shooters are coming to mobile so devs decided to put free legendary skins to global, after all gareena and Chinese players are getting free legendary without grinding for months. But these two items aren't suit a shooter game unlike some hero shooters like valorant/Overwatch etc.
And after season 11 update there are huge amount of bugs in codm.
