so it seems that the original post has again degraded into an arguement between the sheer value of the unit standing alone vs. the value of the unit in the hands of a capable player. In terms of sheer unit value how can you not love a unit like the Praetorian or Red Coat? But more intriguingly (and one of the things i love most about civ) is that in the hands of an experienced player a unit such as the Carrack can provide a devestating edge (granted you'd be playing under certain conditions - otherwise I hate that damn boat). As for an answer to the post I personally have always liked Hwatchas, tough little buggers and it's obviously that seige is one thing you're going to build anyway.
