I'm not necessarily disagreeing with the posts after my initial one. My main point was just that rocket tag (tm) does not exist solely as the purview of high-op or high-level. That, I think, is uncontentious.
Semi-corollary to that statement: rocket tag can sneak up on you. As a DM, it's liberally sprinkled through monsters, sometimes sort of randomly. Setting aside the silliness that is Monster Manual II, you still find it in surprising monsters, especially when it is buried in their spell-like abilities section. The good thing about beholders, wights, and dragons, at least, is that they are well-known to have rockets. That's part of their charm, imho.
As a player, even if you were playing a totally "classic" caster, like you were only using iconic D&D spells, you would still end up with rocket tag after a while what with your Fingers of Death and so on.
