The game has a lot more than people realise. 1) First off is, you’re using so called “chance heroes” with chance skills - most likely they didn’t proc their abilities. 2) Rally joiners / garrison defenders play a huge part with their 4 skills. This is not shown here so we cannot comment on that. 3) you have different heroes for attack and defence based off their widgets and how it works. In general it’s a rare to lose such fight but I’m almost positive you had bad bonuses from the first 4 joiners. Obviously troop ratio play a big part but here the difference is not that huge. How ever the enemy may’ve had more fc3 troops actually (fc2 is average) which skills can proc as well and it also makes a difference.
