That's the point of them, so they are strong. If they're too strong, they could be balanced via VP congress.Voting no. Unique Units are already crazy overpowered; they completely wipe the map with the units that they replace. So much so that often times my goto strategy is: forward expand -> rush unit tech -> declare war and stomp all my neighbours. While there is something to be said for adding more unique units makes every unique unit less unique (and be extension less powerful), I'm strongly against cluttering the map with a bunch of unit variations that have different versions of "+x stat/perk"
