You don't want to use Angel Hair Braid with BB. I'm not sure if it is a bug or intended, but right now Roar and Retaliate proc BB's 30% damage bonus after blocking meaning you won't get it for your shield bash or whatever spending you are using.
This would be for a "Play Your Way" Punish build, amping up Primary damage as much as possible. I would of course HAVE a spender, but it would be something cheap I could spam to get more procs out of Zodiac ring to get the CD on Provoke and Iron Skin as low as possible.
Might even go Sweep Attack and 2pc Roland's to get that 1sec off on attack. Combine that with Holy Shock for the healing.
I would like to see a unique rework on the 2 piece and a significant upgrade on the 4 piece.
On the 4 or 6 piece, I'm looking forward to a similar system as the IK 4p bonus thus ending into a near-perma/perma Akarat's Champion.
We already know that Roland's set is very good and easy to use, what would bring more fun to the crusader is a creative Akkhan set which could work great by itself and that would work into a 4/4 or 6/2 and vice versa.
Not really in the right thread here but Vyr, LeapQuake and Shadows also need some rework and/or 2 additionnal pieces.
