I disagree. You throw a fastball in a slugger's wheelhouse, of course they're going to hit it out of the park. That's what using direct spells on living targets is. You're looking at the absolute best situation for that kind of spell. To continue the analogy, it is when you come up against anything that isn't a living target that direct spells falter, missing that curve that just kissed the outside corner of the plate. A power hitter just can't do anything with that kind of pitch.
In contrast, indirect spells are like the batter who might not get the home run, but can be counted on to get on base more times than not. Single, double, triple, even a bunt now and then. They can fight off the fastball in on their hands, and bring the curve ball on the corner into play. In other words, they are able to make things happen, even when a situation isn't the most favorable for them.
To use a different analogy, I'll go back to D&D. High level spellcasters are some of the most powerful people in the game, it is true, and appear brokenly so if you put, say, a prepared wizard against a fighter in a one-on-one arena match where the wizard has no other fights that day. You're playing directly into the wizard's strengths, there. But put those two in a dungeon crawl together, and the balance shifts, as the fighter takes on the better part of the work, since the wizard must conserve his spells to fight the Boss with. Likewise, Direct and Indirect spells have such a relationship. Put a direct spell against an indirect spell in the direct spell's most favorable situation, and of course it will come out on top. But the indirect spell has far greater utility than the direct spell, and can affect all those things the direct spell cannot touch. This is the point that people keep forgetting, mindlessly harping on the fact that a direct spell is better against a living foe than an indirect, while failing to see that there are weaknesses that direct spells have that indirect spells do not.
Mason, your post reads as follows: "I think Direct spells are more powerful than Indirect, but I also believe that Direct spells should be powered up with things they can't already do."
