I tested Fury on my Human Ranger Tempest (TR'd once from Exploiter, now pure Ranger, no splashes).
I use Khopeshes (most of the time GS Lit II, GS Min II, Drow Khopesh - haven't made myself an Alchemical yet, unfortunately).
The increase in DPS is huge, both steady output and burst.
- Considering that Primal Scream grants a noteworthy increase to STR, and that Fury Eternal keeps Adrenalines going on and on, I have so far never encountered a place where I'm out of either Adrenaline or Scream.
- Unbridled Fury, I tend to use when a big fight is involved, e.g. boss fight, big wave of mobs, etc.
- As for the amounts of damage, that's something I'll leave to whoever likes to do the math; my STR goes up to 42-44 or higher with all buffs, pots and whatnot; an Adrenaline crit usually reaches 1.4k-1.5k, and I haven't seen higher numbers so far. The good thing is that when using an Unbridled Fury I get usually 8 to 10 Adrenaline Overloads, so I'm not complaining or anything.
I know Rangers don't dish out as much damage on a single melee attack, but the point here is the number of attacks, I guess; also, survivability goes a long way: a dead toon deals 0 damage, even if the build is a monster.
All in all, I think the Destiny seems well balanced for Tempest, even though I would like to try Fury Made Placid, when it's fixed (although now that I've tried Fury Eternal I'm not likely to permanently switch).
I was planning to Twist in the ED: In the Weeds (Shiradi Champion, tier 4); Improved Power Attack (Legendary Dreadnought, tier 2); Perfect Balance (Grandmaster of Flowers, tier 1).
What do you guys think?
