Your hero’s have 3 intrinsic stats that you can direcly observe by clicking on them:
Attack
Defense
Health (HP)
Troops modify all those stats, so there will be an increase over what’s on the card when the hero actually appears on the field. But as Kerridoc says, you can read off the current HP for each hero in the green bars on the battlefield.
TP is the stat that’s harder to work out, but Kerridoc has done a simple linear regression that’s not bad:
The thing to note is that each point of defense adds twice as many TP as each point of health. So the effect you’re seeing is actually to be expected. Heroes with high health and low defense will have lower TP than those with high defense and low health. But high health/low defense teams will be worth more war points, because points are distributed on health, not TP.
