Same here. I have been looking at unlocking the AN94 for the past 2 prestiges but eventually just spent them on Awareness and Scavenger.
AN-94 is a good weapon. It's a shame it's a higher unlock but the permanent unlock token does help out alot. Can't decide between the AN-94 and M8A1 once I prestige considering they're both decent Assault Rifles.
How do you find Awareness as a perk? I stopped using soundwhoring perks as I find Tactical Mask & Engineer my favourite Tier 3 perks.
I have found that Awareness helps you know when people are coming around corners but is basically useless if a UAV is up because you already know that they are coming around the corner. I have found that Awareness is extremely useful with Engineer in SnD with 2 Black Hats.
1st Prestige, I got an extra Custom Class and unlocked Scavenger.
Using a token on a gun in this game is a bad idea in my opinion because all the guns are usable, and there are always loads of the ACR, MP7 type n00b guns laying around for an easy upgrade.
Upgrade/Unlock and prepare your perk and equipment set up rather than your weapons.
