An oversight?

It's a tactical game, in those cases like mentioned, the enemy tactics were superior (cheesy as all hell, but superior nonetheless).

And why not? Contests of strategy are contests of information. Knowing who and where your opponents are as well as what they're doing can make or break a maneuver or a strategy. It is true in RTS; it is true in poker; it is true in other turn-based strategy. Failure to understand this makes you weaker in the contest; refusal to accept this is foolhardiness.

YEAH, YOU TELL THEM BUDDY.
HOW DARE THOSE MONSTERS AT IS MAKE YOU THINK!!!
