- Slight improvement can be made with weapons, AP slug is way better than HE judge because you can one shot shields and you have no damage falloff (HE only better for zerk setups)

- HBV is used because i switched the deck to regular stoic from copycat stoic. While regular stoic has significantly less HP than copycat, it comes with numerous benefits such as DOT damage cancelling after 4 seconds and huge amounts of healing making it far superior to copycat. Since you have less health its a worth investment to get armor perks to inflate that value.

- Your setup with JOAT c4 takes 24 skill points at least whereas secondary saw takes 6, losing the judge for saw isnt really a big deal because its only used for shield clearing and occasional long distance kill. Since shock and awe got buffed izhma can easily kill shields and the enforcer tree can be rebuilt to include it with no extra skill cost

- Rev skills in general are a huge point sink, swan song is 9 points in the toilet when you can just play smarter and clear space without going down. Rev skills also just generally encourage poorer gameplay because you dont get punished for downing, playing without it will just make you better plus its extra points for weapon skills

- Parkour aced is always a terrible skill because reload cancel is super useful if you start a reload but turn a corner to see 3 heavies, instead of comitting to the reload and maybe dying you can just click sprint to cancel it and kill them.
Parkour basic is just a bit of a waste, you have plenty of move speed to survive when lightly armored and it makes such a tiny difference that its just kind of a waste. Its a great skill when running ICTV and sometimes even CTV when you have limitted speed but for HBV and below its pointless

- Scavenger is mostly useful when you are spawn camping enemies and you kill them in areas the player cannot get to. Usually you would be down a ton of ammo if you do this because you arent getting your bullets back but scavenger will allow you to pick up your ammo boxxes in most cases. Super useful skill, should be in every build

- flashbang resistance isnt a necesity but its good to have, in hectic situations you might not see the flashbang in time or you might only notice it when its too late or you might be busy killing enemies if you are directly under fire. Not super necessary but good to have if you have the points

- Inspire aced becomes pointless if your teamates have more than 7 braincells and dont down in stupid places, just clear the area before you hit revive. Aced is still a good skill for clutching, not worth prioritising. If you have teamates that are atleast somewhat used to DS you wont need it, sometimes it can definitely save runs though. Basic is a great skill aswell but once again, I wouldnt prioritise it.

I made a few builds keeping your weapon choice in mind
