Assassin's Mark on hit + Vulnerability on hit rings possible?

I have 2 on curse on hit rings, with the new changes to curses and the wording of the mods on the rings I assumed that I could have Vulnerability for general map clearing and Assassin's Mark take priority on rare/unique mobs.

I know that if I want 'both' curses at the same time I need +1 curse but when I tried using both rings, Vulnerability seems to take priority at least visually. I can't tell if both are being applied but only Vulnerability is being shown for some reason.

My Assassin's Mark on hit is also only Level 8, so I don't know if a Level 12 ring would make it take precedence, but it'd currently cost me about 1ex to test this out. I've also tried switching the rings around in my slots but Vulnerability still seems to show as taking precedence.

I found this in another thread but it's going against what I'm seeing in-game, does anyone know for sure what's going on or is it possible to get an official response?

Just figured out
"Additions to the number of curses you can inflict on enemies apply cumulatively to both Hexes and Marks, but do not modify the number of enemies you can have Marked at any given time. Thus, you can have an enemy that is affected by both a Mark and a Hex, but you can't Mark an enemy with two Marks, nor can you Mark two different enemies."

Yep, I can apply a hex and a mark at same time, even without +1 curse item/passive.

Sadly GG....err Tencent basically deleted the Marks, why waste a valuable socket on something with such a limited use? why waste the time using it?

tencent didn't do anything they might meddle financially but they don't have any input in balance you people need to stop blaming every little shit you don't like about PoE on tencent

With the changes in 3.12 you can apply both a hex and a mark without any +curses. They should both be applying.

Wrong.....mark and hex is still curse....

haven't try my dual curse legacy ring, which i am not sure on rare mark or hex is the "staying" curse, however.

This is what I thought should be happening but 'visually' only Vulnerability is showing as being applied, and it's hard to tell just by looking at health bars if both are being applied simultaneously.

I can't seem to find the original statement I quoted in the OP but I'm assuming it's a GGG statement from somewhere? Doesn't the wording indicate that the latest changes to Curses mean that both can be applied simultaneously?

But regardless of if they can or cannot, that wasn't my original question, I guess what I'm really trying to find out is with the recent changes what takes priority. At the moment it seems to be Vulnerability, but if both rings apply 'on hit', following older curse mechanics if Assassin's Mark is being applied first and Vulnerability follows after then we can assume that Vulnerability overwrites Assassin's Mark every hit. But there's no mention of how the mechanic functions now that Vulnerability on hit is % effectiveness and Assassin's Mark is still based on Level, how does the game determine values to override or not?

Tempted in buying a Level 12 Assassin's Mark ring and testing but I'd throwing away 1ex in the name of science.

From what I understand the on hit rings were nerfed for marks because of easy charge generation, which I can understand, but in my case I'm not interested in charge generation but more just the damage modifiers that the Mark's give for bossing. Most builds don't struggle to clear maps but some can struggle to kill bosses, was hoping that an on hit Mark ring would help for this.
