added list is not the same as given usage and can't be equal. It's not like that is the ONLY spell of that level you can cast.
also, why does Favored enemy has 8 instances over 20 levels of Ranger?
Talk about overkill on focusing an entire class on a single (low level) feature.
A spell that is not that great to begin with and no one really likes the spell.
Cast HM and shoot two arrows.
Cast Spike Growth
Recast HM, stow now, draw sword, attack twice.
3 rounds. 3 spells. That's how low encounter Ranger is supposed to play.
