Check the US guides. There is a post on BS/INV I6 death machine type thing on there by Yomo I think.
I'd post my build, but it's in need of some love, and a level 50 respec takes me anything up to an hour before I'm fully sorted. I've been putting it off for ages :/
Basically Invuln has good Def and Resists, 3 slot everything with def/dam res and add an End redux onto every attack and toggle you have, as well as 3 slotting Stamina. You WILL survive on a diet solely of Blues until you can get SO's in Stamina, and even then you'll be wanting to keep a few just in case. I also took Conserve power and always watch for it coming up.
With regards to Unstoppable, I say take it, slot it 3x dam res 3x recharge. Saved my skin many a time, and unlike Regen's MoG you can still be healed and run your existing toggles with it. Also hasten is a must too as BS attacks are quite slow to cycle back. Take Unyielding and Invincibility, as well as Dull Pain, which should be slotted 3 heal 3 recharge. Parry isn't a real necessity due to the high def from invincibility, but you might want to take it to increase the def quite a bit. 3 Slotting Tough hide easily counteracts the -def from the other toggle, which i can't remember the name of!! I didn't bother with the passives but it does make me weak to fire/nrg and Negative nrg, I just rely on DP and BS attacks to hit them hard. It has a knock up, and a knock down, I picked up Air Sup to keep them on the floor as well. You'll get used to the totally mental idea of running right into the middle of the mob so they all count towards your def, and use cover when available to get close quickly. Ranged attacks are not defended against in any way unless you take something else (more end, and you need every drop!) so be careful when picking your fight.
BS Rocks totally, highest resisted damage in the game or not. With a handy Kinetics Defender in attendance, and with the help of Fulcrum Shift I managed a 863 hit with Critical against an even level minion. Now that's got to rock!

Many and varied!
@Miss Chief
Hey, can anyone post me a build for I6? My brother recently gave me his scrapper, it's level 38, and he hasn't used his respec from I6 yet. So I'm looking to respec his build (it's terrible atm...), and take his char up and beyond! So, any help?
