+1 to leveling more slowly. Going from level 2 to level 3 in particular happens way too fast imo. In PnP, you want to level up quickly because low levels are boring as characters don't have many options. But you're controlling a party of 4 in BG3, so you still have lots of options, and being at lower level for a bit longer will help people get a better feel for and understanding of the characters and basic mechanics.

Also +1 to raising the level cap to 5. Not much more to say here; there's been loads of threads dedicated to this.

Larian could have taken this opportunity to rename spell levels to "tiers" or something else. But ah well.
