I have one suggestion - think before posting!
If you want to convince anyone to your arguments don't humiliate yourself with examples that are neither funny or good.
Mindless commanders like Golem vanish! on turn 50, not retreat. They suddenly stop to exist.
As I said, you are the attacked, you win the battle, but do not manage to kill few enemy units. Ha, it gets even worse - your enemy routs, but does not manage to do it before turn 50 [say he has many crippled or low AP ones], so routing triggers for you and you have faster/flying ones, so you rout faster and you lose. Many battles get resolved on turns 30-45, but they need some edge to end properly [routing, killing last units, killing paralyzed units].
