Nah, my time's pretty spot on. All of my perks go off while their stunned.. I simply don't do enough damage to kill some. I blame the low min damage on Shade perks, but well.. that's for a different topic. Here's a damage log taken ~5 minutes ago in the new zone, from an extremely well-geared adventurer.. who I could perk (drained a MP pet) but I know from experience that they don't cycle acro, for some reason.
You hit Arcticangel for 2381 points of Sneak Atck damage.

I cut out all of the shield spam, but they were running RRFE at that time. I'll sum up my damage for you quickly: 11528.
Nothing's wrong with LoSing, I do it all the time. But if you think I'm going to make another pass at an Adventurer, or anyone for that matter, you're mistaken. By the time their def is down, my drains are out and I can't perk them
My argument being that..? Abusing LoS is the only way to beat some classes, or what?
