Lack an understanding of Starcraft. It isn't a rock-paper-scissors games. If you think of the game of units and counters, you will lose. It goes so far beyond that.
I love Starcraft and go to tournaments to play it. My style is I put so much pressure on you, if you wanted to tech to a certain unit (Banshee's for instance), you'd die to my pressure. I force my opponent into a small set of strategies that can hold my pressure, and if they don't do one of those, they die. You can't do anything like that in RTW, it is all about unit positioning, and that means it depends so heavily on the balance between units, which I pointed out with Bull Warriors is garbage. The game should punish people (as Starcraft does) for building too many of X or Y, regardless of whether or not it is trying to be historical. But since some units are simply overpowered it does not, and the games comes off being ahistorical and unbalanced. So it isn't a good game on any front. It can be entertaining, but there really isn't any skill involved, even if both players played the same nation, there is still the blind rock-paper-scissors unit selection phase that has nothing to do with skill. Only if both players select the same units and same nation and play a balance map (like the Grassy Flatlands) can you attribute a win or loss directly to skill.
In Starcraft you can know what your opponent is going for units if you scout, and scouting and attempts to deny scouting or decieve your opponent becomes an entire game in and of itself.
And in Starcraft at a high level, you don't build a unit to counter another unit (he has Roaches, let me get some Immortals), you build a unit to reduce the chances of him building another unit. Great players simply don't mass unit X or unit Y. That of course doesn't happen in RTW too. I speak of Starcraft 2, but Starcraft 1is more the double the age of RTW, so age isn't really a reason for a game to unbalanced.
