I’m a zerg player, so feel free to correct me here. I find my lurkers can struggle against disruptor, especially before quick burrow - I cant clump them anymore and spreading them is extra micro I need to do, which might give you an advantage if I start lapsing my macro. Disruptors also zone out and devastate hydra/ling numbers. They should at least buy you more time to make a protoss deathball.
You could also make a few phoenixes, maybe 2-4, to lift and kill lone lurkers looking to do econ damage or ones rallying across. No need to commit to tech switch into air for phoenixes
Something cheeky I could see, but probably isn’t reliable, is using DT’s and sniping any detection they bring with them. Psionic Storm also deals well with them, if you can get in range - don’t even need detection.
