Rancor Collar Q's

I was just tooling around looking at any post that had info on how to gear WAR for endgame. As my gear set progresses I've often returned to this post to look at what Vlor has listed. Vlor, I noticed you favor Claymore Grip over Pole Grip. I thought I remembered people mathing out that +2% DA would trump the +3% Crit Rate (although this was like 2008 and I have no time to dig for it). Or I could be wrong completely. Is the math different now because of available gear and hard/soft caps? I'd try to math it out myself, but honestly, I struggle to find enough time in my schedule to play as much as I'd like let alone re-up my WAR mathing skills (which have sadly become waaaaaay under-leveled). Thanks for your consideration on what might be an obvious question to those who haven't taken such a long break as I did.
