I never thought "Druid + Natural Spell" counted as being "out to break the game with super uber combos."
And yes, I have known people on this very forum who either personally did this, or personally did things like it, following what made sense for their characters, and bumbling into something that made them stupidly overpowered. The reverse is, of course, dramatically easier, where one player picked things purely because they were enjoying themselves and now find they're being left behind by everyone else.
