Every Single Possible Class I can imagine that wynn could add

Off the top of my head; Not too identical to existing classes. Just so people know their is still a surplus of second spell ideas.
Bard: Instrument
2nd Spell: Chords; summons chords which travel forwards by themself, you can teleport to any of them by hitting them with a melee attack or spell

Alchemist: Potion Rack
2nd Spell: Manifest; Throw a potion which manifests your form

Artificier: Wrench
2nd Spell: Propel; Charge up a powerful leap with power dependant on charge time, shift to release the propel

Barbarian: Battleax
2nd Spell: Vault; Jump forwards with great force, even greater force if you collide with one of your thrown axes (1st spell)

Scribe: Quill
2nd Spell: Ascend; Summon a magical staircase made of words and sigils which quickly pushes you to the top. The staircase becomes steeper if you look higher up.

 

This sounds like awful gameplay

Ah yes, the ender pearl class
