I have played it in a few games and it doesn't seen to be triggering. Its not a particularly popular rune but I am pretty sure it isn't working right. I also have no idea where I am supposed to post this kind of thing.
There's a bugs sub forum here: http://forums.poxnora.com/index.php?forums/bug-reporting.6/ As for the particular issue -- what do you mean by not triggering? Could you elaborate a little?
Combat Awareness (2) prevents non-targeted spell damage and non-targeted ability dmg so a Manslayer with Combat Awareness (2) wouldn't lose Warcharges to anything that doesn't target it.
@Sokolov Is now a good time to request Warguard and its 12 nora cost be removed from Manslayer? Warguard is for cheap champs imo. http://forums.poxnora.com/index.php?threads/deep-elf-manslayer.25324/
when she wasn't bugged was my main deploy on both CA and Deep Wound bg...now she's just to avoid...I hope they fix it soon(or remove warguard)
Imho, Warguard adds a layer of complexity that is not really needed. It could (and should) be removed. Also, are the two unit with it paying for both the ability and the HP? I can count on one hand the time a DEMS get killed via normal HP loss.
