It seems broken. Probably 90%+ of each fight I go into, I don't get a single crit while striking around 15+ times with my weapon. I'm using Recount to monitor my damage.
No, I don't think so... I think you're stuck with me and my "epeen", child. You might even get another chance to ask me for help instead of insulting me for making an off hand comment on something you, apparently, already tested, dummy.
I can say for certain it does work. Maybe a problem with recount. I just set up my 2h toon with medium armor and put 2 points in. I was then able to crit and seen it both in FTC and by health bars losing a bigger chuck.
I also get the full 21% bonus from this passive and it seems to work just fine for me. I get around 30% crit chance in my char screen (I have another passive + a weapon trait that also boost crit) and about 1/3 of my hits do seem to be a critical hit.
