Azraeel, if you're trying to be "aggressive" by attacking the enem'ys main base and essentially raiding it, then the question is not about reclaim, reclaim is an afterthought. Attacking enemy's main base is not exactly "aggressive" gameplay. Aggressive gameplay is spending resources to gain map control. Attack an enemy's main is attempting to "end the game", which inevitably if you fail will yield certain benefits to the defend for a comeback. Its not really worth it, because you're targetting buildings that can be rebuilt instead of the COM which is what you should be targetting to end the game.
Let's unpack this.
It's not "aggressive" to attack the enemy at his strongest point? That's just not accurate. The word "aggressive" doesn't mean anything if it doesn't include a raid or assault on the enemy main base.
You wrote that attacking an enemy's base is not about reclaim. You wrote that reclaim is not a factor to consider when deciding to attack the enemy base. But you also write that an attack on the enemy's main base should ONLY be done as an attempt to end the game, and that an attack on an enemy's base, when it fails, "will yield certain benefits to the defend for a comeback." What are those benefits, other than reclaim? The only benefit that is guaranteed after a failed attack is reclaim.
It's just not true that a failed attack always means the attacker will have fewer units and therefore be vulnerable to a counter-attack. Hypothetically: I could attack your base with 20 tanks, kill 30 of your tanks and two factories, my tanks die, the attack ends. I now have an advantage in the total number of troops even though my attack failed (you lost 30 tanks + 2 factories, I only lost 20 tanks). In that situation, the only benefit to the defender is reclaim. But what a benefit it is. You can rebuild the 2 factories, scoop fifty (FIFTY!) dead tanks, the game is still going. Take away the reclaim and that attack would have been a major success for me.
Why should we only target commanders to end the game, and not target economy? That's not even true on dual gap. Why would anyone make a nuke if it was pointless to blow up buildings? ACUs can easily dodge nukes.
Your perspective is limited by more than just the fact that you only ever play 1 map.
