Heightening incapacitation spells

[Nik Gervae]

In all the fuss I've read over how bad incapacitation spells are, it's easy to see that you can heighten the spell level to overcome the problem. In fact, I've never seen that mentioned in the various guides and discussions. Now I'm sure it'll depend on the specific spell, but since incapacitation spells are acknowledged to be very powerful, are there some you think it's well worth heightening for use against higher-level foes, and are there some you think aren't worth heightening?

I must admit I'm pretty savage on incapacitation myself, but even in my own spell guide I give Calm Emotions my top ranking and recommend heightening it.

Personally I am often challenging my players with higher level opponents because
1) they are a strong tactical group
2) its easier to GM with 1-3 enemies, than a dozen lower level enemies.
So the disadvantage of incapacitation shows up more.

But multiple targeting incapacitation spells are still good. Because it is unlikely that the GM will send a large group of high level enemies after you.

Incapacitation spells also include a lot of things which can be useful when it comes to less murder hobo based approaches. For example, charm can stop a lone sentry from raising an alarm and get him to gladly tell you everything he knows about what's going on inside. And spells like charm and Dominate can remain really effective narrative tools against low level noncombatants.
