Hang on, I'll dig out my guide.
Here
thanks for that 
it was fun before but it looks like SR is going to be improved? not sure if thats good or bad after invul (especially pre I4) i fancied being on the edge of oneshot.
Its already on par, if not better than invun, it will get better in I7 .
I'll update the guide when I7 is released
EDIT: I'm thinking of making another SR when I7 is released, we could have a dodgey duo! 
yeah I miss when invul scrapper was basically a tank. Im hoping to be back on the game (tho limited times as im sharing a pc) in the next week, will have to re-learn everything. Im still going for my plan to have a BS/everything at 50! the other primaries just dont feel right
sigh, SR will be good, Inv will still be ok, Regen is good as always (it didnt get nerfed :O) and Dark is still the odd one out 
.

I thought the effect of the defence changes on MoG are Regen's token nerf for this issue?

I have a spines/sr up to early teens and its fun so far, wondering if anyone has slotting tips for the SR part, is it just 3xdef and end redux for toggles and 3xdef for passives? any other pool choice suggestions would be good too.

2 End Reds, 3 Def in the toggles is my preference, slotting in the passives is as much as you can happily fit in, up to 3 Def (with Lucky being the most easily dropped). Medicine Pool > Aid Self is pretty much a must for a PvP SR, but it's optional (although recommended) for a PvE build.
