Haven't played this game as much as some other members here but still I do consider myself experienced, though lacking a bit in the infantry department
The AI back in old SP2 times WAS Borg-ish a bit, but it was compensated by being not-so-bright. It had to be Borgish to be able to compete atleast with inexperienced PI (Player Intelligence).
Andy and Don made a great effort to bring the AI as close to PI as possible. While doing so they've removed Borginess as it's not needed anymore now the AI can react with its arty fire plan very close to PI.
And the AI dispersion is working right the same way as PI dispersion. Enjoyed myself in one game how AI was lobbing salvo after salvo into thin air where my tanks have once been, Loathed the AI when it started shelling hill behind which my TD's were lurking. But never saw Borgish behavior in SPMBT/SPWW2. Just an intelligent, some times almost human behavior.
