And if they're defending on a Hill, they can build a Pa and get +4 Strength from the Pa PLUS the hills defence bonus PLUS the full fortification bonus PLUS additional healing at the end of the turn.This is why i think the toa is potentially problematic:
Consider Toa vs Shaka's impi corps, generally considered medieval bruisers
40
+10 vs anticav
+5 from haka alpha dominance dance
+8 from oligarchy and legacy
=63.
Impi corps with oligarchy
41
+10 from corps
+5 from shaka's loincloth (zulu corps bonus)
+8 from oligarchy and legacy
=64.
An impi corps costs ~250 production.
Even without using pikes here, Toa can outhit knights by 5 (53 v 48), Black Army as seen so far by 3, only losing to samurai (by just 3) in the middle ages. And the toa can get tortoise to fend off crossbows (and battlecry to be cruel.)
They got some teeth on them jade clubs!

They're OP, but I think it's actually fine. Remember that Maori have their early game development delayed because of their oceanic start. Getting an OP unit is one thing. Pumping out enough of them while behind in number of cities is a whole other story.
