Tat, I don't think this is a "spoiler", but you can give Morrigan (is that her name?) healing eventially as she advances. Also, if you ever go to any place that has mage characters (like the Circle tower) you might chose to add a mage/healer to your group.
Once you get the Tactics AI programming down, you almost never need to pause durring casual battles. Challenging battles, well, I need to pause them most the time; babysitting is more like it, but that's one of the great parts of the game.
Many of the people posting "It's too hard" seem to be from the FPS type games, also, they want to level up as fast as humanly possible (why, in a game like DA, I have no idea), and just rush into mobs swinging and slinging spells, so planning and pausing and strategy are almost "deterents" to their fun. Also, this game has friendly fire, which I'm seeing more and more is another reason people are dying; they are quite literally killing themselves.
