This is a semi-detailed view on the builds followed by links and everything! Enjoy!

• Glaz Build: A build that emphasizes on mid-long range combat with a touch of cqc here and there for harsh situations. Tested on all difficulties and found working. It tries to immitate Glaz from the game Rainbow Six Siege and I think it does so sufficiently! (Might require a rework after the new BETA... but we will cross that bridge when we get to it!)
  Combat Usage: This is a Diver Sniper build. Best at mid-range combat with a varied arsenal to cover all terrains, utilising dodge, crits and sniper precision to kill enemies efficiently, preferably in the least amount of shots. The use of uppers will give you an advantage not only in healing but also staying up in the fight and Rogue will ensure you avoid as many hits as possible, while also absorbing some damage through your lightweight ballistic vest. Last but not least, your Gruber Kurtz in combination with a well placed concussion grenade will allow to clean the area from weak enemies so you can focus on larger prey. Know to adjust your distances and avoid close quarters confrontations with big threats is key to survival as much as picking off the bigger prey from afar.
  
  (Also I sound a bit too excited there on the intro... Yeh)
  
  
• The Arsonist Build: (SHOWCASE BUILD, may not be 100% viable with everything, depending on how you use it, sry ^_^) A build designed around the new sociopath and the usage of fire with it, although not the most optimal, certainly a fun thematic melee build... If the fire axe was any faster I would be using it too. This build is like a toaster burn, in the sense that if you get to close while it's active it will hurt and there will be burns. (I don't think this build will be particularly affected by any upcoming changes, but I will keep it updated if so)
  Combat Usage: Being mostly here as an update showcase does make this a half-good/half-bad build, but still it doesn't lose its efficiency in difficulties up to mayhem (usually). This is probably the most risky of the builds, requiring you to dive in close quarters and deal damage with your flamethrower before having to start the killstreak with your melee weapon (usable melees explained on video). It has medbags as well as drill skills, so if not anything else you will be bringing a good team support with insane melee damage, maxing out at <24000 damage! I plan to upload my newer version of this build next week, so if you find this suboptimal, then you just wait there, I got you covered ;)
  
  (There should be a time stamp to skip straight to the build and melee changes of update 167, if it doesn't work skip to 1 minute 46 seconds)
  
  
• The Ocelot build: This build is focused around the playstyle of Ocelot from Metal Gear Solid 3 and the akimbo revolvers. I did my best to immitate it while also being able to play in the top difficulties with it, hope you will enjoy this simple, yet nice build.
  Combat Usage: Rather similar to the Glaz build, in the sense that it tries to immitate that feeling of combat that tactical games like MGS and R6 are. Rogue with medkits and lightweight ballistic vest, yes, truthfully rather similar to Glaz but what makes it different? Weapons are more concealable, allowing you to play more with your skillpoints and not having to dump them all in dodge/crits. It has more armor, despite the already high dodge as well as inspire (why does Ocelot have inspire? Hey when I saw him command his men in MGS3 I bet they were inspired!). Other skill points spent in sprintfire and higher stability (akimbo revolvers!), the endgame gameplay with this build is: Using your secondary for spamming headshots on weak enemies and using your revolvers for quickly taking down the big bois, concussion can assist you in all these scenarios, especially if you bite more than you can chew. Use cover and take precise hits, you have uppers to keep you up, but that doesn't mean we can use them forever, so when push comes to shove, remember: Tactical Build, it requires tactic and usage of cover, play it likes you would play an FPS game with tighter and more punishing mechanics, to assure the most out of it.
  
  (Now you have 12 shots)
  
  
• Lord Tachanka: Anarchist, machine guns and complete anihilation! This build has it all! Utilizing a defensive playstyle to fight back against any opposition as well as being a good choke holder/pusher, the Tachanka build serves as a mass murdering line holder/pusher that serves out more punishment, the more punishment it gets. Berserker and anarchist combo together for a great synergy of getting damaged only to deal more damage, health is irrelevant as none can break the lord's armor without becoming swiss cheese first. Staying true to the Rainbow 6 spirit, your health will go down fast, but as long as your protections hold, you will be unstoppable! Molotovs are good for quick armor regain and your rezkoye(?) will pretty much 2 shot a dozer after some kills.
  
  
  
• Steakout Massacre: A grinder lightweight vest build with very high damage dealing. There is not much to be said here except for what is on the video. The main purpose is dive-in do damage, run away, deal more damage until you regain and so on. It's a good lightweight build utilising a gun requested by the community and doing great with it. Can play even on higher difficulties with ease and frankly I had loads of fun playing it, so without further ado, enjoy!
