Corruption - 3-2-1
Devastation - 1-3-1
Renegade - 2-2-2
For min/maxing, run +5 condition damage infusions on all of your gear for a free Superior Sigil of Bursting.
I've done a lot of testing and Devastation does give more dps than Invocation but ONLY when you're the only Renegade in your group(you shouldn't be using two Renegades in most raids anyway). If there's another Renegade, make one run Invocation - 1-1-1. This mostly applies to Fractals.
Please note that having a second axe with hydromancy is only a dps increase if you master the rotation. Getting off the swap without losing damage will require piano hands. If your rotations aren't the best, stick with only running mace/axe with geomancy and staff as a 2nd set in CC emergencies.
Also note that this is a top personal dps build and Kalla with Razorclaw's Rage might end up being more dps.
