OK so, I guess I am the odd one out....I am still running 4 PC T19 with Lessons and Soul of the Netherlord. I can't really see me replacing it only because I am LOVING the mix of damage I am getting from running SC with F&B - the shard gen is very nice and I don't even miss Soul Harvest at all. My DPS floats above 1m from time to time but I will also be dependent on some adds (I switch to SH for ST) and a judicious use of havoc but I am having a lot of fun with Destr and the variety of damage dealing.
My logs aren't the best (
