I'm angry because SC2 basically sucked the oxygen out of the RTS genre for those of us who like "S" more than "RT" because now everything must be "Esport-friendly" (read: tailored to ADHD millenials).
At low level, just doing macro/economy right wins the game. Executing a strategy requires so much micro-management and multitasking that's actually unavailable to 90% of the player base. Between low and high level, a mix of "better macro" and better tactics (don't fight in chokes when your race needs space etc.) wins games, not strategy.
OTOH, it's a bit like saying that at intermediate levels, you win a chess game by not being the first to blunder (or seeing your opponent's mistake).
I believe that an RTS game like Zero-K (a TA-like) for instance is more strategic. Your initial factory choice, which determines which kind of units you'll use is a first strategic choice; static defenses are much more important than in SC2 (where they are more or less considered a waste of resources, except for anti-air maybe). TA is based on territory dominance, so holding a point in the middle of the map is important. In SC2, the middle of the map is where the "deathball" vs "deathball" final match typically happens.
