So recently i have been grinding out my attack to 90 for drygores and yesterday i finally reached my goal. But i am unsure of what ability rotation to use, or even if i should use abilities at all and just stick with momentum. 90 att 77 str and 70 deff... Help would be very appriated.

I don't think you want to use Momentum - you do less DPS that way. If you want to do it in a little more relaxed way, I'd set up Revolution for basic abilities. Use the rotation recommended on Wiki (Decimate/Havoc/Dismember/Sever/Barge/Fury) for a start, and add Destroy, Assault, Slaughter for your Thresholds, and Berserk for your ultimate. Fire off Threshold abilities whenever you have enough adrenaline and you're not on cooldown, and Berserk when you run out of Thresholds and hit 100% adrenaline.

 

At least, that's a good strategy for general purposes. If you want to do something specific, i.e. bossing rather than general purpose Slayer/farming mobs, you may have to change things up a little. There are more advanced strategies/abilities, like tendril abilities that damage both your target and inflict some damage back to you, but it may be good to start simple for now.
