Just change the [faction specific knife] kills directive in Force Recon to a knife kills directive. That way those who want to use the slasher and aurax slasher like myself can do it without issue. Also, power knives would be an option as well.
And make partial kills count directive progress. Deal 44% damage = 0.44 points Deal 93% damage = 0.93 points Deal 75% damage with your LMG and 25% damage with your pistol = 0.75 LMG points and 0.25% pistol points. etc. Less frustrations. More fun for everyone. No more having to killsteal. More helping eachother. Make it possible to progress Annihilator directive and deployed AMS kills.
