Redemption: Incas -> Dravidians
will add a weakness to the very strong Incas, will give Dravidians a tool to fight Knight-Siege without tons of food
Bombard Cannon: Poles -> Bengalis
makes Poles very strong early Imperial Age a bit easier to handle, gives Bengalis an option against Skirms
Arbalest: Malians -> Celts
Both without Bracer, Celts without TR too, so a small, not too meaningful nerf for Malians (who can fight ranged units with Cav or Champkarls anyway) and one Castle Age unit for Celts that at least scales a little bit into Imp
Thumb Ring: Portuguese -> Bengalis
Portuguese have cheap Arbs anyway, don’t need to be good then.
Bengalis get at least one regular FU gold unit.
Siege Ram
: Chinese -> Japanese
Chinese have enough options, they don’t need SR-Halb.
Japanese could actually use their Infantry now.
(Hard Mode) Paladin: Lithuanians -> Goths
Lith have stronger Cav and they should be forced a bit more into Leitis, also great Skirms against ranged units, everytime when they get to Paladin it feels ridiculous.
Goths could use them to fill their civ-weaknesses to some degree.
Many Goth-killer-units (such as Cataphracts or HC) die to Paladin.
Still difficult to tech into which would make it a rare but spicy alternative.
(Hard Mode) Bracer: Bohemians -> Teutons
Makes it a little bit tougher for Bohemians to get into Houfnice-Halb, makes them vulnerable to Skirms and at least a little bit to Champs, without making them even worse in early game.
Teutons have some of the hardest civ-losses because they lack it.
