With my setup as Orc/Ud I achieve 44 DPA (w/ armies out) and 177 OPA (i.e. 4x) at a ratio of 1:2 (dspec:elite)
and 67 DPA (w/ armies out) and 134 OPA (i.e. 2x) at a ratio of 1:1 (dspec:elite).
I run 1:1 (dspec:elite) OOW because I'm in a ghetto where I exclusively attack to grow and I tend to get farmed at 1:2 (dspec:elite). At 1:1, I rarely suffer more than an Ambush while bottomfeeding.
e: including 3 raw tpa, which I find comfortable for stealing
