All variables considered with the new systems and numbers TW2 has, I think having a troop simulator would be very beneficial for those long hauls and noble trains.
Before I trusted it, I entered the numbers from a couple old reports, but it seems to be spot on. The moderators will probably come in and say that it's a third party site, so Innogames makes 0 guarantees as to its authenticity or accuracy. I'll just save their time by saying it first.
Idk about this, because it keeps saying half of my units will survive, but my paladin and noble will both die. Not too sure on whether or not this will be true.
It's based off of percentage for survival. If the overall troop count were to lose over 50% of their forces, it rounds up. So in turn, having 1 unit and over 50% chance of mortality, they're going to die.
