Last I remember reading it did. Doomguard's power is based on our stat ratings. So, it doesn't get affected by like lust or 5% haste (% changes), but icm is a haste rating increase. There was a thread or two here about it, but that was...I don't even remember how long ago. I fell out of the loop on things lately.
But that being said, and trying to get back in the loop on things when I went to read any new EJ comments, found
this. Where it seems there's latency based issues on it. Making it not...reliable? Sicne you can't trust things on latency? Still rereading it since I've skimmed through the walls of text picking up words here and there instead of actually reading it.
