Blue
Ravenous Bugblatter Beast of Traal
We playtested Spell Points at several different levels, and the problem spells were you high level or two.
Basically, casters would using their biggest spells all the time - most return for the action spent, nova to reduce the enemy actions (often by inflicting the dead condition) as quick as possible. This lead to short adventuring days. Or at least the casters pushing hard for them.
So I don't have specific lists of problem spells, but a more systemic issue. You may want to still limit the number of the highest two levels of spells the caster can use. Be it by a hard limit per day or per short rest, or maybe breaking up SP to be by short rest so they can't just dump everything into nova-ing.
