I think the only variation on our list, I did not pick the Varu due to not having used them. I have played against India plenty, though; and they are a strong (but slow) unit. In lieu of the Varu, I nominated the Digger. Yes, it's an infantry which is ridiculously late, but with their coastal bonuses, and as AUS you will be probably playing some kind of coastal map or strategy, are really freaking amazing if you need some kind of late game campaign. You can spam out quite a few them with Australia's DOW production bonus, they are amazingly good. Kind of a niche "shiny toy" though because assumedly your game is well down the path to being decided by the time they come into play. The Winged Hussars are amazing for their era, I'm not sure how the extra damage works exactly, if you can't knockback an enemy as far as how it's calculated, but they seem to do HUGE damage in that case (the knockback thing, tactically is pretty situationally useful as well, you can pretty much throw a frontline of an invasion into disarray quite easily. You can knockback the frontline melee units, and send a GG back to the closest city which is pretty much going to ruin whatever invasion plans they had lol). The Minas, while a ship is devastating for coastal maps and how early Pedro can get it. Cossacks are probably much better than they seem on paper... cycle a few of them in and out of the frontlines, and just being cav units in general (albeit somewhat late) make them great. And the Mamluk has been well spoken for already by several posters. I almost feel like I don't have to say much about warcarts, Legions, or Eagles.
