The Enchanter looks extremely nerfed to me. Moving its signature feature, Split Enchantment, down from 10 to 6 is nice, but putting a hard uses/day limit on it is not, and is unnecessary. And Hypnotic Presence now taking up your concentration makes it even more useless than its 2014 predecessor Hypnotic Gaze.
What? That ability is crazy. In a multi-creature fight, for an action you get to remove a creature from the fight. You are now only using concentration to turn a N opponent fight into an N-1 opponent fight, followed by a 1 opponent fight.
It is basically banish as a 1st level spell.
Maybe I understood how strong it was because I used to play an enchanter in everquest - "mez" was basically that effect. Two one-monster fights is insanely easier than a two-monster fight. And while concentration is strong, so is this effect. The force multiplication is nuts.
In a classic 2 creature fight, you focus down one (in say 2 turns), then kill the other (in, say, 2 turns). You take 6 rounds of monster attacks.
If you shut down a monster with this ability, then kill one foe, then kill the other, you now take 4 rounds of monster attacks total. A 33% reduction in incoming damage. Plus, the max rate you take damage is significantly reduced,
and you can take a breather to set stuff up (everyone patches themselves up, readies an action, you trigger them all right after the enemy's turn, then you all go again), possibly completely nullifying a monster's threat.
All for the cost of a 1st level slot and concentration.
It is even cheap enough that if things are going poorly, you can drop concentration and use it again mid-fight to save a party member.
Hell, against a single foe, you can wait until just before they go, use it, have them lose their turn, then whale on them.
