If you’re really going to just stick with sniper rifles and use them accordingly, consider something like this:
You want a lot of points in Killer, because after you gank someone, this will bring 0ne Sh0t, 0ne Kill back on deck as fast as possible (bonus points for dropping consecutive enemies with that kill skill live too).
Precisi0n and 0ptics don’t need that many points (especially if they’re being buffed by a COM) unless you’re using a sketchy weapon at a very long distance… like maximum-Godfinger-damage-with-Vel0city distance. Not that there’s anything wrong with this (I do it on occasion), but try it without those points and see what you think.
Vel0city, unless you’re using the Godfinger, is worth maxing out (especially for the long-distance shots you appear to be going for). Much less leading of moving targets with bonuses to base and critical damage? What’s not to like?
I don’t use At 0ne with the Gun because I rarely ever hip fire (I’m always scoped), but I left a point in there for the reload speed buff. The extra round isn’t generally worth it because you want to be reloading after every shot for the 0ne Sh0t 0ne Kill buff.
As was mentioned above, if you’re only using sniper rifles, I’d skip Tw0 Fang.
I have points here in Killing Bl0w, and Grim to get to Execute. Inevitably, enemies will rush you, and there’s nothing like having Killing Bl0w and Execute on deck to dispatch enemies that get in your face. Grim’s shield and cooldown buff is just my favorite skill on the way down. Remember that if your Execute doesn’t kill the enemy, they will be stunned with their head down (for humans anyway) right in front of you for a free shot with your sniper rifle.
Have you rolled with Critical Ascensi0n yet? It takes some getting used to if you’re going to try to actively maintain a stack of over a dozen without just letting it happen by luck. It adds up fast though, so I’d say it’s still worth it.
I don’t see any Jakobs weapons in there (although one of them looks like a Muckamuck)? I figured I’d see a Pimpernel and a couple of Sniders (and I’m happy to see the Morningstar), but Zer0 can rock the Buffalo or Elephant gun. Fun fact: with the Buffalo, the crosshairs appear when you go into Decepti0n, and while the zoom is no ball of fire, that gun is very accurate. With the crosshairs available, during Decepti0n, it’s a beast.
