I can speak for Dravidians vs Portuguese/Bohemians matchups. Dravidians have a tough time with Organ Guns and Hussite Wagons. Please note that I have played only one game as Dravidians against Portuguese and no games against Bohemians after the April PUP came out.
However, I have specifically tested Dravidians vs Portuguese/Bohemians on Arabia pre-patch several times. But why? Because Dravidian Light Cav sees more purpose in such matchups than elsewhere. It works well, at least for me, to use Light Cav (Dravidians) cost effectively against Organ Guns/Hussite Wagons.
Yes, in matchups against any Dravidian units except Mangonel-line. I’ve never used Mangonels/Onagers against OGs and HWs though.
Wasn’t this the case before? Guess, that’s why I don’t use archers and infantry (and Urumi Swordsmen) against OGs. Dravidians Champions with Wootzsteel are also not that effective, since they are not Champskarls.
Elephant Archers are also useless. Both HWs and OGs are like tankier Skirmisher-Rams, and you know how much damage generic Skirms deal to Ele Archers.
And Hussite Wagons block arrows, I mean they protect the units behind them from arrows. Both OGs and HWs have high Pierce Armour and deal high Pierce damage. So, more reasons to not use ranged units against them.
Yes, Cavalier/Paladins and Hussars work.
Dravidian Light Cav (with Wootzsteel) also works but will die pretty badly to castle fires and Halbs.
Dravidian Battle Elephants are weak - prone to conversion (Bohemians is a Monk civ), longer production time, poor mobility, no bloodlines and Elite upgrade.
Use your 25% faster-firing Skirms (against enemy Halbs) and position them close to your castle(s).
But let’s see how Dravidian Halbs compare with Portuguese and Bohemian Halbs. Both Portuguese and Bohemians have fully-upgraded Halbs.
In Castle, Portuguese and Dravidians have generic Pikes. In Imperial, Dravidian Halbs have a bit more edge than Portuguese because of Wootzsteel.
In case of Bohemians, their Pikes are superior to Dravidians in Castle thanks to their Civ Bonus (Spearman-line deals +25% bonus damage). Even in Imperial, Bohemian Halbs are better than many other civs’.
Organs guns now are unbeatable by archer and infantry civs without siege onagers. Bombard cannons might seem like a solution, but remember that Portugese have cheaper bombards with ballistics. I don’t see how I can handle these as Dravidians
Both Portuguese and Bohemians are gunpowder civs. For civs without good cavalry, countering HWs and OGs with generic gunpowder units is problematic. Hope these civs, especially Dravidians, get better options to counter OGs and HWs.
They have trouble dealing with siege units in general. Devs game them cheaper siege. But the problem still exists because of poor mobility. HWs and OGs are produced faster, move faster, and a bit cheaper and tankier than Dravidian siege units. So Dravidians siege units are actually inferior.
So, I would suggest the Dravidian player to use cheaper Onagers, Wootzsteel Light Cav and Elite Skirms in a combination against OGs and HWs. (It is still better if you raid your enemy in Feudal and manage to slow down your enemy from building castles.)
Your Elite Skirms will take care of Halbs. Onagers and Light Cav will help snipe OGs and HWs. And BBCs destroy castles.
You should have around 10 stables, 10 ranges and a couple of siege workshops, and slowly push with castles.
Bohemians don’t have good stables and ranges, but Portuguese. If you see Portuguese/Bohemian player go OGs and Cavalier, you may go Onagers, Elite Skirms and Urumis. Urumis are produced faster than your barracks units and are affected by Wootzsteel, but just use them only against Cavalry.
If you are in a stalemate with Portuguese in Imperial on Arabia - where the Portu player has safely hidden some Feitorias and has a castle very close to your castle - you have a bad luck.
In conclusion, Organ Guns and Hussite Wagons are deadly to Dravidians.
Dravidians answer to Organs and Hussites are Onagers and Light Cavalry which are quite inferior.
If the Mangonel-line doesn’t trade off better with OGs and HWs after the latest patch, Devs need to help these Infantry/Archer civs in some way and/or might consider nerfing Bohemian Spearmen-line and Portuguese Knight-line.
