Firstly, the Gurkha has a 1.5 Damage Bonus to villagers and hero if the game is not begin at explore age. I doubt that maybe the group just use the data of EP because the Gurkha in EP in explore age has a 0.5 Damage Bonus to villagers and hero. just like the Fig. below.
And another bug is that, after transport the shipment “Royal Green Jacket”, the Gurkha will have an excess 2 Damage Bonus to all of the infantry(OMG). Which also means Gurkha will have 6 Damage Bonus against Heavy Infantry! WTF!
AOE team please look into this one. This bug is game breaking and unhealthy for the state of Rank games. It definitely needs a HOTFIX x5 vs musk in total and x2 vs any other infantry seems like a bug or too broken
