Other than Last Ditch Effort, those are all skills that I use with Axton (and there’s nothing wrong with LDE, it’s just not my thing). I have tried this build, but I’m way too enamored with Double Up for the slag source to be able to part with it for too long. If you’re not playing in UVHM, it may not be as big a deal; if you are playing in UVHM and you part with Double Up, you have my admiration as a Commando.
However, double Nuke turrets is quite fun. I think people may have an unrealistic expectation that Nuke should flatten everything within it’s blast radius (and maybe that is how it was actually supposed to be), but you can really toss enemies around with it regardless, and it definitely stuns them for a strategic advantage. In Digistruct Peak, I regularly used Nuke to push enemies off cliff edges (this took some practice to get down; maybe you’ve got the chops to get it down right off the bat, but it took a couple of days for me). Also, if you’ve got a big 'ol enemy on your tail, and you want to put him into a specific location, two Nuke drops lets you bounce him fairly adeptly. With two of them and full points in Resourceful, you can recall your turrets right after deploying them and triggering Nuke to drop them again fairly quickly.
If you can live without the slag, I think this build will be quite fun.
