If you don’t use zodiac WC will be bad. The amount of fury you need is going to be large. With the Fjord, we are going have 19 FPA and if you use EF up to 13 FPA. Each attack should require around 8-10 fury based on how much RCR you have.
Fury is going to be an issue that is going to take a bit of time to figure out what works best.
Right now I am leaning towards getting rid of Ruthless and going with Weapon master with Fjord, EF and the templar. With weapon master we not only get more fury but we also get an extra 5% crit chance so we will loose very little dps from getting rid of ruthless.
Edit: no crit bonus for mace in the off-hand.
