Are giants really a good counter to poison arrows? I can see that giant militia might be ok, but then they'll rout for sure due to the constant wounding and morale checks. Better quality giants will die quite quickly to the vast amount of accumulated poison and will almost certainly cost more than the archers.

I have the same doubts about troops with regen. Unless they have extremely high hp or regen percentage there is no way they'll be regenerating enough to counter all the poison they'll be hit with. They are definitely better against poison than units without regen, but I don't really see that they're a counter.

Undead, poison immune troops, archers etc do all work pretty well, though archers of course can have the usual problem of decoys - this applies to the androphag archers too so that's fair enough.
