Ice lock challenge - 100 kills on freezing enemies

I just wish the devs or whoever is making these challenges, would come to their senses and at least test them before putting them in the game for players to complete. i tried my **bleep** off and only got 5 kills in a Full Conquest game.

As a matter of fact, i'm starting to think the devs just ask ChatGPT or some kind of AI to generate challenges based on the game mode without even specifying how difficult they are to complete...
