Upheaval should still be used on cd, because 450 potency ogcd for 20 gauge is a lot better than 590 gcd for 50 gauge, even with the cd reduction to infuriate. You should skip a use of it only, if it drifts outside of your IR window, to realign it. Onslaughti suseful, if it gets you another gcd and sometimes gets used to dump your beast gauge, allthough the later doesn't happen often, normaly only after the opener.

Onslaught is in a really awkward place atm, it costing gauge on one hand ,it costing gauge helps to make the WAR rotation flow really nicely, but on the other hand it messes with it and it is somewhat of a potency loss if used too freely.
