I checked out [MENTION=55582]Treantmonklvl20[/MENTION] guide and here's what I see rated below situational use.
Burning Hands
Disguise Self
Illusory Script
Jump
Arcane Lock
Dust devil
Crown of Madness
Hold Person
Continual Flame
Melf's Acid Arrow
Aganazzar’s scorcher
Snilloc’s snowball swarm
Glyph of Warding
Summon Lesser Demon
Wall of sand
Bestow Curse
Feign Death
Vampiric Touch
Erupting earth
*These are only the level 1-3 spells
I don't find most of these spells to be spells I never would cast, most are just spells that the right situation to cast is rare. Having more spells like that should mean the right situation to cast at least one of them is no longer rare.
Melf's Acid Arrow
Aganazzar’s scorcher
Snilloc’s snowball swarm
Would make great first level spell.
Vampiric touch as a level 2, would take another look.
It would be a bad idea to change hold person. It is a good spell.
