grief/lastwish phase blade combo frenzier... Effective?
Hello fellow barbarian users, if you didn't get it from my title I plan on slapping my newly obtained PBgrief and my favorite sword, my last wish pb, on a frenzy barbarian. I've spent time reading about frenzy mechanics, and I think this outfitting will be great for bosses AND small fries alike.
I've tried frenzy before and it's an awesome skill. I'm a big fan of speed (hence the phase blades haha), but I never did much damage with frenzy. My first question is:
*Will the grief transfer all of the +damage (357 damage in this case) to each weapon swing, or will it be taken into account even when my lastwish hand swings? (like how just holding grief adds to a smiters smiting damage)*
If in fact the damage is universal, this combo will be amazing. with the might aura, 39% ias on my grief (which will be my primary weapon, the only weapon who's ias is taken into account if i understand correctly. I'll be maxed at 5 attacks/second) and the 70% cb from my last wish, I should be able to destroy the usual zombies and oblivion knights with ease along with bosses and ubers. My second question is this:
*Does the crushing blow from my Last Wish only count for swings with the Last Wish, or is it also counted for grief swings as well?* I'm fairly certain it's only for LW, but I'd like to be sure.
Thank you for help and opinions

... I'll also wear (in case you're curious) an archon plate CoH, arreats, 20ias blood gloves, gores, dungos, and an ammy to be named later...
