I think this is a good place to mention my fire emblem thesis. In the first five fire emblem games, the Rng worked with one random number that determined hit or miss. The results were based on the stats of the characters, but still there was a lot of randomness involved, and players felt like the games are not really fair. Since fire emblem six there are two numbers that are generated and the average of them is the generated number. It means that your chances are improved but there is still a random element to the game, but it's still feels more fair. More details here: https://fireemblem.fandom.com/wiki/Random_Number_Generator
I think some solution like this would benefit the game immensely, if Larion doesn't want to remove the system altogether

"74.85% of you stood with the Tieflings, and 25.15% of you sided with Minthara. Good outweighs evil, it seems."
