Yup! But in terms of civ design. Giving a tropical region an amour bonus is just silly. That’s true for Bengalis and Malay as well. Though I agree, this bonus along with last amour will he greate for Dravidians gameplay with light cav and Elephant archers. There are easier ways like how bulgarians are designed with Militia line free + cheaper blacksmith upgrades. I think Dravidians could get 50% cheaper attack upgrades at the Blacksmith. As a civ that made ‘wootz steel’ historically, they should get some bonus from blacksmith for the attack upgrades. They will get forging, iron casting, Blast furnace, fletching, bodkin arrow and Bracer 50% cheaper. This will also mean the timing of the attack can be earlier than other civs. M@A can sustain more time. Skirms can also quickly get +1 over other civ skirms. The current 25% faster is frankly not enough for a low DPS unit like skirms.
Barracks technologies and blacksmith attack upgrades cost -50%.
I’ll just requote something I wrote an year back.
