As you can see I haven't been very lucky with weapons yet. I have good ancient ones that is for sure, but I have had 4 torches drop that have all rolled really poorly and I've had two furnaces drop below 3400 dps. From the tests I did the low roll furnaces didn't out dps my high ancients.
I really like the law of seph setup. I stack about 54% CDR on all the characters which allows me to round robin Blinding Flash Self Reflection every 1.78 seconds. This keeps the RG and other bosses permanently blind. Nothing like fighting statues. EP for the quick clears. Once I get half decent torches I will swap to a Wave of Light Build (either fire or lightning depending on the situation).
Currently I am using Hellfire Rings and Cain set for the massive 95% xp buff. Once I hit over paragon 400 I may change that. I can't really swap to leroics or rubies in the helm or I will lose spirit and the cdr I need to blindlock bosses.
I use 3 guys with dps skills and the fourth uses Cyclone Strike to bring things in range of LTK. I also use a Nemesis Bracer on the LTK character in order to summon more elite/rare packs in GR's.
So far so good, My guys are a little bit squishy still atm, but I am working on fixing that by leveling up the new gems.
