Being very well conversed in the history of India, Indian warfare and weaponary during the 15th to 19th centuries, i am astonished at the lack of Indian factions.
The Mughal Empire comprises the only Indian faction, and after having reviewed your campaign map i feel there is space for one more faction. The truth being, the Mughals did not control all of North India. The Sikhs were a constant thorn in the side of the Mughal Empire and i think the Sikhs should be at least added, even if it is just simply a minor faction. Towards the end of the 1700 (where your mod ends) the Sikhs had forged their own Kingdom in the nothern India, and was on the same scale as those seen in Europe. So i feel the Sikhs should not simply just be a rebel band, they should have their own minor faction.

I hope you consider my proposals and i will glady help the developers with the development of the Mughal and (if added) Sikh faction.
