We already had the Indians, now they wasted an entire DLC on splitting up an already existing faction?! That is…. Disconcerting. We need the Greeks, Irish…. Not more Indian Factions. They were fine as is. Even the North American Indian tribes would of been fresher. Or Egypt with some Numerian Spearmen. Bah……
Nope, old Indians were trash historically and unit diversity-wise. A civilization that used camels instead of horses, didn't have melee elephant units and had hand cannoneers didn't exist ever. To count that civ as Indians makes as much sense as having a civ that is a mix of Brit+Scots+Irish or a ''German'' civ that's a mixture of Teutons+Goths+Sicilians.
Medieval Greeks=Byzantines, Numidians=Berbers during the Roman timeframe, Egyptians during AoE2=Mamluk Sultanate, medieval North America north of the Aztecs=boring. Irish could be interesting though. More Asian factions would be interesting as fuck. We still don't have Tibetans, Turks are one entity instead of Seljuk and Ottoman, the whole of the Asian middle east is just ''Saracens'' and Persians (ie Sassanids) and even more Indian civs can be added. Considering the vast timeframe covered in the campaigns (ie Huns, Goths and the fall of Rome to late 1500s Imjin War), a unified ''Chinese'' civ doesn't make much sense either.
