Basically, I find myself running Eviscerate when I have a cap sig or two on my bar, and Dismember + Cleave otherwise. Against things like cobalt mokele and diamond djinn, I swapped to Whirling Axe to get around their high armor.
Eviscerate
ProSpiky. Deep Wound + damage Frees up skill slots Con8 adrenaline Spike not too important in pve
Cleave
ProGood DPS Relatively cheap (4a) Reasonable +dmg, close to Eviscerate ConNo deep wound Adrenaline inefficiency
I've even run Whirling Axe a few times. It's absolutely junk in PvP because it is a dps skill with a horrible disable clause, but in PvE you can build against the monsters at any point.
ProVery cheap (2a) If spammed, high armor-ignoring component of damage (+21s add up) ConDisable clause Huge adrenaline inefficiency No utility or Deep Wound
