so I'm a little concerned about the new barb set. I'm gonna think out loud here. 2pc - 300% dmg to rend....ok awesome but then 4pc - 300% duration...uhhh...doesn't that totally negate the 300% dmg? lets say my normal rend does 10,000 dmg over 5 seconds. 2pc bonus is now giving me 30k dmg over 5 seconds. awesome. 4pc bonus tho suddenly makes me do 30k dmg of 15 seconds. ya. That completely negates the 2pc bonus. Its not like its hard to cast rend. This would be the exact same as casting rend on a mob 3 times over 15 seconds. The only good thing is that I can cast and forget making the whirlwind bonus easier to take advantage of. but it seems dps wise this will be quite weak. i just played around with rend/whirlwind...keeping rend up is actually a pain in the arse. So perhaps their main goal here was to allow rend to last a lot longer without nerfing it. I feel they need to do more with this set tho to make it elite. they should combine the 2pc and 4pc into a single bonus and add something else that is cool to this. ESPECIALLY since its a 6 pc set. Something like rend or whirlwind gain all runes. fury generation with this combo is gonna be odd. I was blowing thru fury in my test pretty fast. (but i was having to cast rend every 5 seconds) I had to use charge to keep fury going without disrupting the rhythm. the rend belt will certainly be a must on this set for double rend.
