Bug challenge and gadget shotgun fire shell

Hello BF6 community, thank you for this great game. I just wanted to mention three things: a small bug and a suggestion regarding the Assault class. 1. There's a bug with the Shotgun Fire Shell gadget. The 5k damage challenge with this gadget only counts the shot damage, not the fire damage. Reaching 5k damage to complete the challenge is nearly impossible. 2. It's the worst gadget in the game; it's useless. It's impossible to get a kill with this weapon. To get a kill, you have to land four direct hits. It's a weapon that's practically useless and nobody uses it. My suggestion is to adjust the challenge; it's very difficult to complete. Second, improve the weapon, as it's useless. Using this weapon is pointless for the challenge; it's a guaranteed death sentence. I only do the challenge because I want to get the Assault Master; otherwise, this weapon or gadget is useless. Thank you very much, and keep up the great work with this awesome game.
