Are the extra 6 movepoints of Human Musketeer compared to Ballistae worth it?
Solution 1:
No, musketeers are one of the absolutely pointless units in the game. He is basically an archer with a better ranged attack and when you can have a unit like the cavalier, what reason is there to produce an archer?
The musketeer is squishy, helpless in melee combat and his ability isn't very strong. This is not what you want and need from a tier 3 unit. Just give them a wide berth.
