Amazing chill build for levelling with PUG / non-coordinated teams below Tier 3 (Malice) / low intensity T3 or to help friends levelling up. Especially in situations whereby your teammates do not like to stay close to each other for team coherency. Amazing sustainability, survivability as well as good damage output.
Your positioning will be at the back (in a corner without enemy spawning) or at higher grounds with good line of sight. You're playing into the advantage of Camo Expert heavily (will detail below). This build is good to elimate non-armored elites, specialists etc at range. Most importantly, you don't need to “compete” for ammo with others because you have high ammo reserves.
Power Sword is amazing to clear/cleave horde enemies, just use light attacks, also remember to activate it before using the sword for increased damage. The cooldown between activation is barely noticeable. Rampage + Slaughterer is INSANELY GOOD combo on the sword.
Camo expert is amazing for those players who came from FPS-based games - if you jump on top of boxes / raised platforms, the enemies will walk past you (most of them, not all) and hit your melee team mates instead. It is crucial to STAY STILL and don't use your movement keys. This gives you better chance to focus and snipe down elite/special enemies and is especially good if your team mates are constantly scattered (no coherency). If your team has an Ogryn or MORE, he/she'll not be able to ass-block your view lol. Camo Expert is an amazing “passive defense” feat that synergizes really well with At Arm's Length, Sniper and Covering Fire if you're standing high above at a distance from enemies.
Counterfire is overall better because it has better damage output but if you're still struggling to survive, go for Sustained Fire. You shouldn't have any toughness issue. If you did, swap between Confirmed Kill or Exhilarating Takedown - whichever works better for you.
For the gun's blessing - it's hard to get those two blessing combos in max tier for now. If you cant, I find that Falter + Infernus is another amazing combo when you pair with Duck & Dive and Deadshot for feats.
