Yeah, but how does well does it work in the field?

I didn't consider Haste *too* broken until I bought this module. That's when I noticed that just about *every single NPC* carried a Potion of Haste. Hell, most spellcasters even had a Haste memorized in case that potion ran out during combat.

This indicated that the module's authors felt that the only way to deal with Haste was...more Haste.

No other spell has such an issue.
