This game has a myriad of problems, but one of them isn't randomness, unless it's because it's too random. The PCs are all underpowered and too difficult to make better. The stamina/magic system is intriguing, but recovery is too slow to make the game flow well (far too many discards). Sure, you can play a level any number of times and eventually beat it, but that's just luck. Make it less luck and more tactics, and people will like it much more.
