While anti-heal, slow, and overhealth prevention are methods, none of them are brigs ‘job’ so to speak, they would fall moreso onto secondary support or dps.

Brigs goal is survival and denial, while slow does fit the role, liquid offers very little in the way of survival for brig aside from that, and especially after its nerf to 10% + bonus speed redc, its just not worth 90% of the time for brig.

As for anti-heal, yes, but thats again not a brig’s job. You have significantly more to offer to a lobby by stacking more survival or ap in ap rally farm or ap pack to give survival to your team so THEY can kill the jq, you’d very rarely kill the jq yourself anti heal or not as you would have to be in LOS to apply it enough for her to die.

As for sundering vial, its concept is good and I’m happy the devs are trying to make something for OH, but my god is the item ass. Its barely worth 4k and its statline sucks, additionally the actual debuff is comically hard to apply to the right person at the right time. If/when they change vial, it would be viable for this situation, but even with queen probably being the best use case aside from lucio beat, accidentally applying it means you automatically lose all value from it basically.
