If we look at a decent range-focused roll True Prophecy and use it’s range as a sort of control (because Ace’s range is higher than most 120’s I’m pretty sure), Ace will still come out on top as it’s TTK is much faster than that of True Prophecy. Ace is cracked in terms of range and to me it feels much more sticky than any of the 120’s, but I’m not sure that’s actually true.

Next point, damage perks. Ace’s Memento Mori is absolutely insane for stuff like Trials where you’re not going for huge multi kills - because it doesn’t run out, so you’ll have that buff ready and waiting for your next engagement without being on the clock. With TP’s rampage, yes you can get that crispy 2-bang but you’re gonna be pressured for time and, providing you can hit your shots, Ace’s TTK with Mori active is still better than a TP with Rampage.

The only way I see TP being consistently better than Ace is the fact you can slap an Icarus mod on it for those floofy kills. But, if you’re a warlock with Heat Rises (like we don’t see enough of these guys) then Ace still comes out on top.

(Oh, plus Ace has cool ornaments)
