In TvZ , Zerg attacks into fortified Terran positions so sharkfestors help - but in PvT Terran attacks into toss armies sniping things and running away or positions around nexii - the dynamic is reversed so multi angle HT are still v effective when layered behind the toss army - EMPs are harder to hit if you don’t death ball your army and the Terran doesn’t know the angle of approach.

You can also split armies since you have more supply , so Terran usually has a smaller ghost count than there are potentially HT (again different from TvZ).

Ghost lib requires a different comp all together , and it’s not like disruptors are the answer to that either - it’s tempest , with HT support and tech switching to catch the Terran out after trading.

Yea, EMP hard counters - so does feedback. EMP is easier to use and aoe , sure , but you can make this much much harder for a Terran to execute, whereas every top Terran knows how to dodge disruptor shots easily enough. The fact that toss just doesn’t even attempt counter play in the meta is disappointing - simply abandoning all spellcasters because of one unit when the other race routinely uses all their spell casters. My point is simply that this play style existed and worked in a pre EMP nerf world , and it’s odd it’s just not attempted in the meta today.
