I mostly want level 5.
There are a lot of level 3 spells that could go REALLY wrong without some proper feedback and balancing.

Stuff like animate dead, conjure animals, counterspell, fly, major image, ... come to mind.
Depending on how exactly they implement this, animate dead for example (especially with the necromancy wizard, that is in the PHB) could completely break the game, in ways that shatter just can not.

Summoning in general is a "problematic" category of spells that starts at level 3 and so can only be playtested for player feedback if we get another level.

Also, I want to see how exactly extra attack interacts with a couple Larian features!
