You're weaving a false narrative. A half-damage fireball isn't going to take down a pair of level 5+ fighters unless they're already severely injured, at which point you can just do what every other sorcerer without Careful Spell does - choose a different spell. Careful Spell makes friendly fire a more tactically viable option, not the preferred or default option as you seem to be suggesting. As for Circle of Death, the solution is obvious: don't select that spell. The smaller area of fireball makes it more suitable for a larger number of scenarios, and fireball cast as a 6th level spell does a lot more damage besides.
Ignoring all that, would it help you get past the Careful Spell discussion if I went back to edit my post and say mitigate instead of negate? My original point was that he ought to avoid AE damage centric builds. The mention of Evokers and metamagic was just an afterthought in case he did want to focus on that style of casting.
Back to druids, the bottom line is that he asked for the broadest range of spells available. A druid doesn't have the sheer number of spells to choose from as a wizard, or the damage potential of a sorcerer, but in terms of actual variety of effects (which includes healing), he's better than either of them, and CotL does spells better than CotM. There's nothing to argue.
