By all means, feel free to offer suggestions to Larian about how you would like to see the game work. That's fine and good. But perhaps take fun facts 1-3 into consideration before jumping to conclusions. There is perhaps a connection between fun facts 1, 2, and 3.

Fun fact 1 : You cannot have a mage hand and a familiar at the same time
Fun fact 2 : Larian already did everything that they could to destroy casters in BG3. HP bloat, spell nerfs, ultra limited max level...
Fun fact 3 : Larian never had a game with good necromancy

Larian has a LOT of resources. If they din't allowed us to see the tier 3+ spells is cuz they are debating if they will """balance""" or not(read : Balance = Ruin and force everyone who wanna a more P&P experience to use a mod like spell fixes for nwn2)
