With the Advanced Tactics mod, I only micromanage the mage in Dragon Age.
In Baldur's Gate, I simply gave all characters missile weapons, set their script to ranged and micromanaged the mage & cleric to occasionally buff and throw an offensive spell. The reason why Baldur's Gate 2 came up with those ridiculous thousand-and-one spell protections, was to prevent for the game to be played on autopilot.
Both games are far from the paragons of tactical combat they are presumed to be.
