Made a few changes, I probably added around 150 million in costs to the build but it will definitely benefit. I'd suggest later on saving up for more Luck of the Gambler's to replace Serendipity.

Dark/Shield Build Thread
I can't actually afford an extra 150 million inf, I currently have around 180 million and only a few of the IOs I need from reward rolls. So I definitely won't be dipping into LotGs yet, and I don't understand why you put an extra recharge on practiced Brawler 
Last night I actually went to WW to check some prices and realised a few of the IOs were al ittle out of my reach so here's my new, revised, cheaper build. It's also in the OP.

Hey guys, this is a continuation of another thread I started where I was asking about a simple SO build, but I've now decided to IO out my scrapper
If you'd like to read the other thread its here.
The main builds I need opinions on are these:
Whisky Jack's build: DataLink!
My edit: DataLink!
BTW, can't thank you enough for that build Whisky Jack, you're a genius!
