You know, thinking it over, I'm honestly not sure. Those Direct Crits do cause a substantial spike we mostly lack in our rotation as we average around 300 Potency when it comes to our skill flow. However, we just don't know the value Det brings in this new setup. It may be better to push stable damage above spikes in our case, because we're a bit more evenly distributed for our damage outside our Melee Phase.

I do personally lean more towards dHit/Crit build for the most visible return, but I don't do extended stat trials.
