You're not making sense, freudqo. Stunbolt (which is merely the best example of the direct/indirect issue) doesn't need to 'ram' things, because it's already awesome at dropping people (which is not 100% of all situations, but certainly many). There are comparatively few situations where 'stunbolt just isn't enough', and fewer still where an Indirect Elemental spell *is* a better option.
And no, they shouldn't take worse spells; the point is that other spells would ideally *be* rational choices. The problem under discussion is specifically that Stunbolt *is* the supremely rational choice. As NiL pointed out, Stunbolt is very frequently better for nonlethal *and* lethal, which is just one more point in its favor.
And, yes, it's 100% about variety and balance. The idea is that it's a waste when one option is vastly better than other options, to the point that they're barely used. This is not a controversial or novel idea. You're trying to trivialize it, but it *is* about fireballs being cool. They're cool enough that it would be nice if someone had an actual reason to use one.

To repeat: this is all optional, as everything is.

If you do not share the ideal that one item, spell, category, tactic, etc. should not be overwhelmingly and mechanically predominant over its immediate peers, no one is making you change your rules or fluff. The OP, however, asked this exact, specific question: 'is the heavy drain for fireball, the light drain for stunbolt, coupled with their relative utility, a problem?'
The "-1 drain code for stun damage" mechanic does probably mean that if mages take only one combat spell Stunball is almost always the one they choose. Stunball will probably also be in most mages' repetoires if they have 2, 3 or more combat spells as well.
Saying that, there *are* times that Indirect Combat Spells shine, namely in affecting unseen targets, damaging drones, and (as hasn't been emphasized enough thus far) those
secondary elemental effects. Going back to Falconer's Powerbolt/Flamethrower vs a combat drone example, only the direct damage from the spell was considered. For example ammo does not react well to fire, especially Magical fire, and might well explode. So, although the Powerbolt is a defeat-the-OR-all-or-nothing spell, the Flamethrower will pretty much always do *some* damage to the drone,
and have a fair chance of causing all its ammo to explode (possibly causing it more damage and preventing it from firing back).
As Yerameyahu pretty much admits, most folk who balk at the drain of indirect combat spells are the guys who want to throw fireballs all day long and are allergic to taking drain, which for the most part they won't have to do when overcasting Stunbolts left, right and centre. Use a fetish, live a little and learn to live with drain sometimes!
If your GM remembers to take the secondary elemental effects into account, indirect combat spells are *not* nerfed IMHO. But as we can see from the length of this debate, YMWV.
