Spell Points

[MaxWilson]

Yep, it is a great increase in flexibility.

It's particularly great for warlocks because it prevents 80% of the warlock list from becoming obsolete trash at later levels. E.g. Mirror Image out of a 5th level slot is pretty bad, so bad you wouldn't take it, but with spellpoints you still have the option to cast it as a regular 2nd level spell. Ditto Hex. There's still the concentration opportunity cost to consider, but at least the spell list itself doesn't feel like it's shrinking.
