I think P-47 just needs to clump its rockets together. It's weird when the strategy to getting hit with p-47 is to do literally nothing because rockets will pass to your tank's sides.
Its anti-infantry is tied to its vet 2, which is contrary to its doctrine of spammability because you have to babysit a tank until it reaches vet 2 when you should be able to do well with multiple vet 0 tanks.
Heavy Cavalry is good, but Firestorm just sounds cheesy. Ugh. I wish Incendiary Field Support won. It was the most accurate name. Or Incendiary Assault at least.
