How to deal with defences as Jumpbots?

When playing jumpbots I have difficulty dealing with defenses, especially the stinger + stardust combo.
- Puppy cant do much against stardusts. Dregs idea of cloaked puppies dosent work well against screening units like fleas.
- Similiarly pyro dosent do well.
- A huge group of moderators can take out a stinger but cant make cost. Also, moderators have mediocre range, so the stardust also does a lot of damage to them, if not killing them.
- Jack would be the standard response of going assaults vs defenses. But jack has poor speed and range; A group of bandits and/or skirmishers is just plain bad news for a jack. You can't use pyros against raiders because pyros are expensive and dont have a lot of hp and will easily get killed. The fire created on their deaths will only burn the jacks.
- Jugglenaut + jack is very expensive.
- Firewalker is the artillery unit, but unfortunately it takes a lot of time for firewalkers to kill a defence. If there are caretakers which can constantly repair the defence and/or if there is an aegis then the firewalker cant do much.
- Iris-cloaked skuttle also wont work against screening units like flea.

If anyone has any helpful strategies please post it.

Jacks with placeholder support.

JJ are hard to play solo, work a lot better as a support fac.

Jacks are their only unit that is really good at killing defenses. They do tend to get pounded a lot by everything around when acting solo, but they have one of the best health-for-cost ratios in the game. They're meant to withstand a pouding.

If you feel you can't afford a frontal attack with jacks, gradual attrition with firewalker is your other main option.

Make jack + scuttle if the enemy has expensive turrets (desolator/Cerberus/lucifer)

First try to go around them. Forcing your opponent into making defenses is often as much as you can hope for with jumpbots.

Study early game porcwars (aggressive Picket/Lotus) to make opponents unable to spam light defenses freely. Use Constable aggressively to help with this.

Predict when heavier defenses are about to arrive and try to get a Firewalker to the relevant location by the time they do, so as to not fall behind the buildup. Constable may allow you to skip a few pre-emptive Lotuses.
