At the time of this post I have not yet reviewed the battle posted. However, I will add my 2 cents.
Pyro is a superior raider to bandit, and should be treated as such. 4:1 bandit-pyro ratio is good but avoid clumping or pyro will kill.
Shield has no true riot, which means expanding as shield is problematic. I would suggest, in my experiences against people with better raiding skills than oneself, to invest more into Lotus rather than bandits.
Remember the disadvantages of porc:
Cannot move, ergo cannot attack.
Advantage:
Better stats for cost.
The disadvantage of not moving is irrelevant if having more raiders is not beneficial - namely, if you would lose 2 bandits for no gain just invest in lotus.
Do not neglect bandits, but rather, focus more on static defense and use bandits to defend key points such as mexes or base, and try to fight within porc to minimize losses. You will expand slower but it is better than not expanding against an opponent with better raiding skills/raiders.
This way you avoid crippling raids in the early game. Lotus does not scale well, but by that point you shohld be past pyro raids.
Mid and late game shield has good chances to win. Rogues drastically outrange moderator, which means attrition free kills, and are of help against Jack and Jugglenaut: Both units are quite slow.
ThugFelon should be kept in reserve, but piling them up is not the best idea, because Jacks will drain felon and thug shield, leaving them weak to anything that shoots at them. Instead, have enough felonthug to deter pyro attacks and invest more into rogues, which crush any attempt at skirmishing that jump can bring.
If you do go felonthug, which is a fair choice, bring bandits to prevent jacks from wiping out felon.
Go slow and build up. Shield's entire gameplan is to get so big, tanky, and have enough firepower likho can be shot from the sky, mino hp is drained within seconds and no amount of porc stops it. This cannot be done if shield is taking losses on the attack.
