My SR brute can do it.
Testing my shield tank right now. She died. Since I was testing as I did with my SR tank and brute, that meant no clicking hasten. Which meant AD stopped being doublestacked, which meant cascading defense failure which meant death. Course she probably wouldn't have died had I just kept clicking hasten. Testing that theory now. Yup, as long as hasten is backing up AD, I'll sit at 87.8% DDR. No CDF. And that's with AD only single slotted with a 50+5 recred,
Don't currently have a shield brute to try it. Even with the lower resistance levels, it should be ok, too, as long as AD remains doublestacked. That's *IF* the DDR values are the same. I honestly don't know.
Yea, SR sucks so much. /insert painful eyeroll here.
