the stats are tricky, and it should probably be replaced by the Double Crossbow.
Nah, that's the part where I have to disagree. The core book double crossbow is a mess of worthlessness. A "trap option" in every sense, which I have great difficulty believing was anything but deliberate design. It requires more training and feats than a simple weapon, performs far worse, and completely breaks down the moment additional attacks are available for other options even though multiple attacks are the primary method of growth for martial damage dealers. It is also very expensive.
Some look at the handful of exotic weapons that are particularly powerful and say "They have to be better because they require additional feats and training to use effectively". They look at the repeating crossbows and say "Well crossbows are a simple weapon so they must not be as good", get reminded that these are exotics, and "oh well not all weapons are created equal lol".
Fact is, game systems require consistency. The standard Double only works to hamper and hold-back a character, and no amount of "but you can still choose it for roleplay reasons" makes how badly it screws the character okay. The Minotaur Double may not be ideal, but it works within the system and its use can grow along a character.
