People who think spike growth is good haven't seen AI or the player trivially jump out of it or a Hunger of Haddar or Darkness. The idea that terrain matters is a joke when 80% of the boots by Act 2 and Act 3 give immunity to difficult terrain and some outright immunity to being ensnared/enwebbed.

And a Hold Person is a joke, wasting a spell slot and concentration on something you can achieve with a Crawler Venom or Drow Poison. Both grant more reliable, less costly CC and autocrit. On spammable consumables.
