I think these days playing cloaky is less about glaives and more about their slow units. The buffed warrior and zeus should have a good time vs. pyro without while also just being all-round solid.
When they start making a skirm army (moderator+placeholder), you add in spectre and maybe more glaives.

Also, vs. JJ, plopping down pairs of defenders is good practice as any fac. Two defenders will kill a pyro for 160 metal without any losses, and is worth 400 metal in puppies, which makes raiding/scouting impossible unless they're willing to commit 400+ metal. Once they're able to field that kind of army, and send it in blind vs. radar, I imagine ticks with 1-2 glaives are a good investment for punishing the over-extension.

This feels like a growth match-up to me, not a heavy raiding one. Similar to amphib fac, JJ often finds it easy to attain raider superiority, but it takes considerable mistakes on the opponent's part for them to be able to get much damage done to the base.

Oh, and I really liked Dahn's expansion path this game. Not sure whether it was the right choice given the situation, but it was interesting nonetheless, threatening to cut kshatrya in two while also claiming the majority of the map.
