What is the utility of Onslaught and Upheaval?

[Kyni]

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.

How does that work? It costing gauge makes me want to use sprint to get to the mob instead of using it, because at the end of the day it's 20 gauge that could be going to a fell cleave. Also it costing gauge makes me unable to use it to initiate fights.

That's why I can't see its utility, there is no incentive to use it. Sure it feels great, but its cost outweights its utility.

Sprint does have a 60 seconds cooldown and is not instant so you still might lose a gcd even while sprintig and that would still be at least a 200 potency loss (in case of losing only a heavy swing), while onslaught is just shy of 20 potency loss comapred to spending the gauge on fell cleave(haven't realy mathed it out, but it's very unlikely to be even in the same ballpark as the 200 potency you gain at a minimum from the additional gcd). So yes, onslaught is a dps gain, if you get a gcd out of it.

The other use case ( Gauge managment) might allow you to better allign your burst with raid buffs, for example you should always be aiming to get 2 IC 1 FC and 1 Upheavle under trick ( except when IR is ready at the same time). But this is a more advanced usage of it and is only very rarely benefical, so don't overthink it.

To sum it up: Use Onslaught during IR and when you would gain a gcd from it and you should be good.

Shouldn't Onslaught be changed as to not use gauge and Upheaval be changed to actually be useful?.

Can't tell if you're trolling about upheaval or not. Fell Cleave is 590 potency for a cost of 50 gauge, which is 11.8 potency per gauge point (590/50). Upheaval is 450 potency for a cost of 20 gauge, which is 22.5 potency per gauge point (450/20). In other words, upheaval gives you more damage per gauge.

Use upheaval on cooldown. Onslaught is situational. I recommend https://thebalanceffxiv.com/ and it's associated discord for any further questions.
