It may have already been said but i didnt read through all 7 pages :)
I found that right now (I'm at about 1.95 AS) and with LL dont refresh archon all that efficiently (decent, but not great in low mob density) but previously when I was more like 2.3 or so, LL was a beast at resetting archon
*Dont mind my profile, I was trying out WW w/ storm crow. I will say that with 2.0 AS or less, i find archon refreshing faster with WW than with LL.
I dont recall how quick UBR's bosses refreshed with LL, but with WW/stormcrow its refreshing pretty quick.
I am however very annoyed by the AP draining of WW and it makes popping archon slower since many times AP is out and have to wait for it to refresh...that delay has made for a few close calls thats for sure.
Net - I think i'll get more IAS gear back and get back to a 2.2-2.3 AS w/ LL build.
