Jumpers so needed that buff

I was ahead in useless shield army which could do precisely nothing against superior jump guys.

Anarchid: The Constable buff wasn't why you lost this one though (your bandit happily crashed Steel_Blue's eco and his constable army died horribly to actual riot units).
It was using Felons against a Jugglenaught rather than Rogues or Racketeer spam (Jugglenaught vs Felons is a very hard counter).*
Bait out the jump with a pair of Rogues then move in another half dozen from a couple of angles.
Or three Racketeers and some bandits to mop up.

If your opponent rushes a heavy unit (to the point when that single unit is more than half your entire army size) then you will might need to spend a bit to come up with a specific counter if you don't already have it.

* Doubt anyone would blame you for not realizing at the time that you needed to keep your army running away until you had a Juggle counter, it's not a common interaction and there are so many other counters to be aware of (as I'm reminded every game when someone pulls out something I don't know the counter for).

When jumper late game comes out facswitch for Penes

Anarchid:
Econ killing wasn't be too much of a concern given how slow the Jugglenaught is and the fact that it and placeholders aren't very effective against buildings. :D

Actually that reminds me, what was your reasoning for making three Felons? A Felon's limiting factor is very rarely its (obscene) DPS, but generally its shield charge. I can't imagine what possible realistic unit combination jump could field that would need 2400 dps.
I'd have gone for a Felon, an Aspis and a pair of thugs instead of three Felons if I was sure I'd be facing mostly raiders and riots. Probably have put a few Rogues too to fend off skirmishers and because Rogues are dirt cheap.

Musings:

I wasn't thinking of the mixed felon+aspis+thug+rogue army being better against Juggernaught, I was just wondering under what circumstances 3 felons are needed.pull a felon that has an escorting (G)uarding it.
I was indeed thinking of thugs as a source of shield charge as they have better shieldhp/cost than the convict and more importantly they transfer shield a fair bit faster and have almost double the shield regen rate. Though I was mostly thinking of them as some protect for attacks from within the Aspis shield bubble.

I hadn't thought of just how close the moderator and Felon ranges are... I guess DPS really starts to matter when it's only a 15 elmo difference.
Though when I tried sandboxing it, I found that 3 Felons (1860) only barely scrape a win vs 6 moderators (1440) and one died, while the mixed ball (1 felon+1 aspis+2 thug+2 rogue=1820m) got a much more comfortable win (no losses) and became combat effective more quickly afterwards.

From my testing Felons generally do around 2-3k damage to the Juggle before getting mulched and so are very cost inefficient.
My mixed shield ball did a bit better but also died. Though at least with the latter if your enemy miscalculates or you see them coming you can do some rogue skirmishing.

At this point I was thinking "Hmm... Shield seems to lack a good counter to Jugglenaught."
Then I remembered Dirtbags are a thing. :D
Reckon spamming a line of Dirtbags (with the occasional Rogue) at that Juggle would have worked?

The idea is that the dirtbags do damage when the Juggle smashes them into itself (which is the main way it attacks*) not via DPS. Each dirtbag will do ~600 damage that way.

* A Juggle that's pushing is a mostly harmless Juggle that you can pound with Rogues.
