Throwing knives and Mortars

I really like those gadgets in previous installment of the Battlefield but in BF6 they are underperforming hard. 

Throwing knives should 1 shot people - its ideal weapon for stealth takedowns. In current build you need to make a headshot or throw ~3 knives to the body to kill somebody.

Morar shells (both arlilery and smoke) has some non-existant range of hit. You can score like 1 kill in 10 mins of firing and im pretty sure by accident. They dont hit and kill people like at all. Smoke on the other hand simply dont work, i think, the cloud of smoke also doesnt exist, so its just useless ammo type.

Those two are very cool gadgets but in current state they has 0 use and reason to pick them.

Can we move the balance the other way?
